All About Pyjanitor’s Methodology Chaining Performance, And Why Its Helpful



Picture by Editor

 

# Introduction

 
Working intensively with knowledge in Python teaches all of us an essential lesson: knowledge cleansing often does not really feel very similar to performing knowledge science, however quite like performing as a digital janitor. This is what it takes in most use circumstances: loading a dataset, discovering many column names are messy, coming throughout lacking values, and ending up with loads of momentary knowledge variables, solely the final of them containing your ultimate, clear dataset.

Pyjanitor supplies a cleaner strategy to hold these steps out. This library can be utilized alongside the notion of technique chaining to rework in any other case arduous knowledge cleansing processes into pipelines that look elegant, environment friendly, and readable.

This text exhibits how and demystifies technique chaining within the context of Pyjanitor and knowledge cleansing.

 

# Understanding Methodology Chaining

 
Methodology chaining will not be one thing new within the realm of programming: really, it’s a well-established coding sample. It consists of calling a number of strategies in sequential order on an object: all in only one assertion. This manner, you needn’t reassign a variable after every step, as a result of every technique returns an object that invokes the subsequent hooked up technique, and so forth.

The next instance helps perceive the idea at its core. Observe how we’d apply a number of easy modifications to a small piece of textual content (string) utilizing “normal” Python:

textual content = "  Whats up World!  "
textual content = textual content.strip()
textual content = textual content.decrease()
textual content = textual content.exchange("world", "python")

 

The ensuing worth in textual content might be: "whats up python!".

Now, with technique chaining, the identical course of would appear like:

textual content = "  Whats up World!  "
cleaned_text = textual content.strip().decrease().exchange("world", "python")

 

Discover that the logical circulation of operations utilized goes from left to proper: all in a single, unified chain of thought!

If you happen to obtained it, now you completely perceive the notion of technique chaining. Let’s translate this imaginative and prescient now to the context of information science utilizing Pandas. A typical knowledge cleansing on a dataframe, consisting of a number of steps, usually appears like this with out chaining:

# Conventional, step-by-step Pandas strategy
df = pd.read_csv("knowledge.csv")
df.columns = df.columns.str.decrease().str.exchange(' ', '_')
df = df.dropna(subset=['id'])
df = df.drop_duplicates()

 

As we are going to see shortly, by making use of technique chaining, we are going to assemble a unified pipeline whereby dataframe operations are encapsulated utilizing parentheses. On high of that, we are going to not want intermediate variables containing non-final dataframes, permitting for cleaner, extra bug-resilient code. And (as soon as once more) on the very high of that, Pyjanitor makes this course of seamless.

 

# Getting into Pyjanitor: Software Instance

 
Pandas itself affords native assist for technique chaining to some extent. Nonetheless, a few of its important functionalities haven’t been designed strictly bearing this sample in thoughts. This can be a core motivation why Pyjanitor was born, based mostly on a nearly-namesake R bundle: janitor.

In essence, Pyjanitor could be framed as an extension for Pandas that brings a pack of customized data-cleaning processes in a way chaining-friendly style. Examples of its utility programming interface (API) technique names embody clean_names(), rename_column(), remove_empty(), and so forth. Its API employs a collection of intuitive technique names that take code expressiveness to a complete new stage. Moreover, Pyjanitor utterly depends on open-source, free instruments, and could be seamlessly run in cloud and pocket book environments, comparable to Google Colab.

Let’s totally perceive how technique chaining in Pyjanitor is utilized, via an instance by which we first create a small, artificial dataset that appears deliberately messy, and put it right into a Pandas DataFrame object.

IMPORTANT: to keep away from widespread, but considerably dreadful errors because of incompatibility between library variations, be sure you have the newest out there model of each Pandas and Pyjanitor, through the use of !pip set up --upgrade pyjanitor pandas first.

messy_data = {
    'First Identify ': ['Alice', 'Bob', 'Charlie', 'Alice', None],
    '  Last_Name': ['Smith', 'Jones', 'Brown', 'Smith', 'Doe'],
    'Age': [25, np.nan, 30, 25, 40],
    'Date_Of_Birth': ['1998-01-01', '1995-05-05', '1993-08-08', '1998-01-01', '1983-12-12'],
    'Wage ($)': [50000, 60000, 70000, 50000, 80000],
    'Empty_Col': [np.nan, np.nan, np.nan, np.nan, np.nan]
}

df = pd.DataFrame(messy_data)
print("--- Messy Authentic Information ---")
print(df.head(), "n")

 

Now we outline a Pyjanitor technique chain that applies a collection of processing to each column names and knowledge itself:

cleaned_df = (
    df
    .rename_column('Wage ($)', 'Wage')  # 1. Manually repair tough names BEFORE getting them mangled
    .clean_names()                          # 2. Standardize every thing (makes it 'wage')
    .remove_empty()                         # 3. Drop empty columns/rows
    .drop_duplicates()                      # 4. Take away duplicate rows
    .fill_empty(                            # 5. Impute lacking values
        column_names=['age'],               # CAUTION: after earlier steps, assume lowercase identify: 'age'
        worth=df['Age'].median()            # Pull the median from the unique uncooked df
    )
    .assign(                                # 6. Create a brand new column utilizing assign
        salary_k=lambda d: d['salary'] / 1000
    )
)

print("--- Cleaned Pyjanitor Information ---")
print(cleaned_df)

 

The above code is self-explanatory, with inline feedback explaining every technique known as at each step of the chain.

That is the output of our instance, which compares the unique messy knowledge with the cleaned model:

--- Messy Authentic Information ---
  First Identify    Last_Name   Age Date_Of_Birth  Wage ($)  Empty_Col
0       Alice       Smith  25.0    1998-01-01       50000        NaN
1         Bob       Jones   NaN    1995-05-05       60000        NaN
2     Charlie       Brown  30.0    1993-08-08       70000        NaN
3       Alice       Smith  25.0    1998-01-01       50000        NaN
4         NaN         Doe  40.0    1983-12-12       80000        NaN 

--- Cleaned Pyjanitor Information ---
  first_name_ _last_name   age date_of_birth  wage  salary_k
0       Alice      Smith  25.0    1998-01-01   50000      50.0
1         Bob      Jones  27.5    1995-05-05   60000      60.0
2     Charlie      Brown  30.0    1993-08-08   70000      70.0
4         NaN        Doe  40.0    1983-12-12   80000      80.0

 

# Wrapping Up

 
All through this text, we have now realized use the Pyjanitor library to use technique chaining and simplify in any other case arduous knowledge cleansing processes. This makes the code cleaner, expressive, and — in a way of talking — self-documenting, in order that different builders or your future self can learn the pipeline and simply perceive what’s going on on this journey from uncooked to prepared dataset.

Nice job!

We requested, you answered: Android customers decide between gestures and 3-button navigation, and the best choice may shock you


When establishing a brand new Android cellphone, you are typically given the selection to make use of gestures or 3-button navigation, an possibility you’ll be able to all the time change later within the settings. In a current ballot, we requested whether or not you like to make use of gestures or 3-button navigation in your Android smartphone. Surprisingly, it appears lots of you may have sturdy emotions about this, as our ballot obtained over 19,000 responses.

Based mostly on the responses, it appears Android customers overwhelmingly favor the 3-button navigation, which obtained 81% of the votes. As somebody who was initially skeptical of gestures however has since totally embraced them, I discovered this considerably stunning.

White Home price range seeks to scrap 54 main NASA science missions

Consultants discovered that the White Home price range request for the upcoming fiscal 12 months may defund 54 NASA science missions, together with a spacecraft presently learning Jupiter and two deliberate Venus missions

An evaluation by the nonprofit science advocacy group The Planetary Society has recognized 54 NASA missions which may be endangered on account of the White Home’s price range proposal for the approaching fiscal 12 months. These embrace a spacecraft presently learning Jupiter, a veteran X-ray observatory, deliberate missions to Venus and U.S. collaboration on a European rover meant to launch to Mars in 2028—and lots of extra.

The price range proposal is for the fiscal 12 months 2027, which begins October 1. The proposal slashes funding to the company’s science program by 46 p.c—a reduce just like what had been proposed within the president’s price range request for the present fiscal 12 months. White Home price range proposals are usually not binding; within the case of the present 12 months, Congress finally walked again the steep cuts, appropriating a complete of $24.4 billion for the company for the present fiscal 12 months. Because of this, only one mission was canceled in that closing price range: the Mars Pattern Return, which though a high science precedence, is broadly believed to have develop into infeasible.

The brand new White Home price range proposal for NASA—which totals solely $18.8 billion—didn’t explicitly specify initiatives it meant to cancel.

On supporting science journalism

If you happen to’re having fun with this text, contemplate supporting our award-winning journalism by subscribing. By buying a subscription you’re serving to to make sure the way forward for impactful tales concerning the discoveries and concepts shaping our world at present.

However Planetary Society consultants analyzed this and former documentation to determine which missions could also be at risk. Of NASA’s main science departments, Earth science and heliophysics might face essentially the most cuts, with 17 proposed mission cancellations in every, they discovered. Astrophysics and planetary science every face 10 cancellations, in accordance with the evaluation.

NASA declined to touch upon the Planetary Society evaluation and highlighted a letter from administrator Jared Isaacman included within the full price range request. “The FY 2027 President’s Funds Request displays a transparent precept: america should lead in house, not just for discovery, however for nationwide prosperity, safety, and inspiration,” that letter reads partially. “With the assist of Congress, NASA will proceed to push the boundaries of exploration, strengthen American technological management, and be certain that the subsequent nice chapter of house exploration is led by america.”

Among the initiatives slated for cancellation within the request are ongoing missions. For instance, NASA’s Juno spacecraft has been orbiting Jupiter for simply shy of a decade; the New Horizons probe has revealed the secrets and techniques of Pluto, Charon and the one Kuiper Belt object ever studied up shut; and the Origins, Spectral Interpretation, Useful resource Identification and Safety–Apophis Explorer (OSIRIS-APEX) spacecraft, which delivered rocks from the asteroid Bennu to Earth in 2023, is now getting ready to review the massive asteroid Apophis simply months after a 2029 Earth flyby through which the asteroid will fly nearer to Earth than geosynchronous satellites.

Future science missions additionally face stark losses beneath the proposal: NASA’s Deep Ambiance Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) and Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy (VERITAS) spacecraft to Venus might be canceled, the evaluation finds. So would NASA’s participation within the European House Company (ESA) Rosalind Franklin Mars rover, which NASA agreed to launch after Russia’s invasion of Ukraine dissolved the partnership that initially conceived of the mission.

Different worldwide partnerships may additionally endure, in accordance with the report. The price range would withdraw assist for the Laser Interferometer House Antenna (LISA) mission, meant to deliver gravitational wave science into orbit, and the Superior Telescope for Excessive Power Astrophysics (ATHENA) X-ray observatory—each ESA initiatives that the house company hopes to launch subsequent. The U.S. may additionally withdraw from the operational ESA-led Euclid telescope for darkish matter and darkish power and the Japan-led X-ray Imaging and Spectroscopy Mission (XRISM), in accordance with the Planetary Society.

Different potential cancellation targets embrace the Chandra X-ray Observatory, which after practically 1 / 4 century in house stays essentially the most highly effective X-ray telescope, in accordance with NASA, and the Fermi Gamma-ray House Telescope, which is equally essentially the most highly effective observatory of its class.

Heliophysics missions presumably at risk of cancellation embrace the Photo voltaic and Heliospheric Observatory, which is a partnership with ESA and has offered helpful observations of the solar’s exercise for 30 years. And the dual Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) probes, which research magnetic reconnection in Earth’s ambiance, may additionally see cancellation, in accordance with the evaluation.

In Earth sciences, eight Cyclone World Navigation Satellite tv for pc System (CYGNSS) satellites that measure floor wind speeds in growing tropical storms to facilitate forecasts, and 4 Time-Resolved Observations of Precipitation construction and storm Depth with a Constellation of Smallsats (TROPICS) satellites that assist monitor tropical storms may additionally be focused for cancellation, in accordance with the evaluation.

A number of different focused missions monitoring greenhouse fuel emissions and local weather change, together with the Orbiting Carbon Observatory-2 and its successor (OCO-2 and OCO-3) and the 20-year veteran Aura satellite tv for pc, the evaluation discovered.

LaCy: What Small Language Fashions Can and Ought to Study is Not Only a Query of Loss


This paper was accepted on the Workshop on Reminiscence for LLM-Based mostly Agentic Programs at ICLR.

Language fashions have constantly grown to compress extra world data into their parameters, however the data that may be pretrained into them is upper-bounded by their parameter measurement. Particularly the capability of Small Language Fashions (SLMs) is restricted, resulting in factually incorrect generations. This drawback is commonly mitigated by giving the SLM entry to an outdoor supply: the flexibility to question a bigger mannequin, paperwork, or a database. Below this setting, we research the elemental query of which tokens an SLM can and may be taught throughout pretraining, versus which of them it ought to delegate through a token. We discover that this isn’t merely a query of loss: though the loss is predictive of whether or not a predicted token mismatches the ground-truth, some tokens are acceptable in that they’re truthful various continuations of a pretraining doc, and shouldn’t set off a even when their loss is excessive. We discover {that a} spaCy grammar parser might help increase the loss sign to determine which tokens the SLM ought to be taught to delegate to forestall factual errors and that are secure to be taught and predict even below excessive losses. We suggest LaCy, a novel pretraining technique based mostly on this token choice philosophy. Our experiments exhibit that LaCy fashions efficiently be taught which tokens to foretell and the place to delegate for assist. This leads to increased FactScores when producing in a cascade with a much bigger mannequin and outperforms Rho or LLM-judge skilled SLMs, whereas being less complicated and cheaper.

YouTube is ‘wanting into’ further lengthy advertisements in TV app


TL;DR

  • Customers report seeing unusually lengthy advertisements that may’t be skipped when watching YouTube movies by the service’s TV app.
  • YouTube says that these longer advertisements usually are not intentional and that it’s “wanting into” what’s occurring.

YouTube is funded primarily by promoting, so Google’s incentivized to strike a steadiness between the advert technique that generates probably the most revenue attainable and one which customers received’t discover too obtrusive. Studies this week that customers had been seeing non-skippable, 90-second-long advertisements on YouTube’s TV app appeared to indicate that the corporate was struggling to string that needle — however now, Google says these super-long advertisements aren’t intentional.

Early this month, a number of customers reported that YouTube’s TV app was displaying them longer non-skippable advertisements than the service’s advert format guidelines enable for (YouTube advertisements can get fairly lengthy, however these that may’t be skipped are formally capped at 30 seconds). At this time, the TeamYouTube account on X acknowledged the studies, saying that the habits isn’t intentional and that YouTube is wanting into the offending advertisements.

Don’t wish to miss the most effective from Android Authority?

google preferred source badge light@2xgoogle preferred source badge dark@2x

The tweet not solely clarifies that YouTube isn’t meant to serve advertisements on this manner, but in addition says that the 90-second non-skippable block “isn’t one thing we’re testing proper now.” Taken at face worth, YouTube’s statements right here make the longer advertisements appear unintentional.

YouTube doesn’t have a 90-second non-skippable advert format. This isn’t one thing we’re testing proper now. We’re wanting into this additional.

It’s price noting that YouTube’s been recognized to indicate customers non-skippable advertisements that go effectively over the streamer’s acknowledged 30-second restrict. In a 2025 Android Authority ballot, about 87% of greater than 8,600 respondents indicated that YouTube served them non-skippable advertisements longer than 30 seconds, with practically a 3rd of contributors saying they’d seen non-skippable advertisements go on for longer than two minutes.

It’s unclear how so many customers are experiencing advertisements that apparently violate YouTube’s phrases; optimistically, the platform’s purported investigation into these newest rule-breaking advertisements will get it sorted out.

Do you watch YouTube with advertisements? Have you ever ever encountered a single, non-skippable advert that stretched longer than 30 seconds? Tell us within the feedback.

Scientists Announce The First Clear Proof of a Chimpanzee ‘Civil Conflict’ : ScienceAlert


Deep within the rainforests of Uganda, scientists have watched the most important identified group of untamed chimpanzees (Pan troglodytes) activate one another, as if partaking in a ‘civil warfare’.

The deadly battle is the primary clear instance of a ferocious fission in a wild chimpanzee group – which fractured into two warring teams.

Over a few years, scientists watched as wild primates that when lived, ate, groomed, and patrolled collectively step by step turned on one another, in the end changing into deadly rivals.

As one in all humanity’s closest dwelling relations, these chimps and their social interactions might assist us higher perceive the evolutionary roots of ‘warfare’ and ‘peace’ in our personal societies.

“It’s tempting to attribute polarization and warfare that happen in people at the moment to ethnic, non secular, or political divisions,” clarify the examine authors, led by evolutionary anthropologist Aaron Sandel on the College of Texas at Austin.

However these primates haven’t got the identical causes for in-fighting. As a substitute, plainly shifting social relationships also can drive a wedge between primates of the identical tradition.

“This examine encourages a reevaluation of present fashions of human
collective violence,” Sandel and colleagues conclude of their paper.

frameborder=”0″ enable=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=”allowfullscreen”>

Their proof, extracted from over 30 years of observations, contributes to a decades-long debate. Within the Nineteen Seventies, the late primatologist Jane Goodall seen a group of chimps in Tanzania splinter into two rival factions, resulting in a four-year-long deadly battle.

The reviews turned well-known worldwide as a stunning instance of non-human ‘warfare’, however the particulars have been restricted, and a few critics have since argued that the battles solely occurred due to meals sources equipped throughout Goodall’s analysis.

Chimp Attack
Western chimpanzees encircle a 36-year-old male, Basie, from the Central group in 2019. Basie (middle) was killed on this assault. (Aaron Sandel)

Chimpanzees might be grotesque killers, and within the wild, they’re identified to assault different neighboring teams, presumably to defend and increase their territory or to raid assets. However whether or not chimps of the identical cultural group interact in civil ‘warfare’ has been much less clear.

The genes of chimps, for example, counsel that everlasting fissions inside teams are exceedingly rare – with an occasion occurring each 500 years or so.

This latest instance in Uganda could also be one such rarity. Again in 1995, Ngogo chimps in western Uganda’s Kibale Nationwide Park have been a part of a single, massive group.

Then, in 2015, simply after a brand new alpha male had been topped, primatologists seen an inexplicable shift.

Two clusters of chimps started to take form throughout the identical group, and mating occurred solely between women and men of the identical cluster or clique.

“Our first behavioral observations suggestive of a cut up occurred on 24 June 2015, when members of the Western and Central clusters approached one another close to the middle of their territory,” the analysis staff explains.

“Somewhat than reuniting in typical fission-fusion vogue, the Western chimpanzees ran away, and the Central chimpanzees chased them. A 6-week interval of avoidance adopted. Such a protracted interval of avoidance had not been noticed earlier than.”

What was as soon as the middle of the Ngogo chimp group turned a border, patrolled by males from each side. Then, in 2017, social pressure got here to a head.

The Western group was a lot smaller than the Central group, however it initiated all of the assaults. That yr, Western chimps battled and severely injured the alpha male of the bigger Central cluster.

By 2018, the rupture between these two cliques had turn out to be everlasting in social, spatial, and reproductive phrases. The females and offspring would now not even feed on the identical fig tree.

A couple of years later, in 2021, the aggression turned to infants. Researchers instantly noticed Western chimps stealing and killing 14 infants from the Central cluster.

Between 2018 and 2024, Western chimps would assault and kill a mean of 1 grownup male and two infants a yr.

Such killing charges far exceed these which were estimated for intergroup aggression amongst chimpanzees, the authors say, and there might have been extra.

Over time, greater than a dozen Ngogo Central chimps died resulting from unknown causes. Usually, these apparently wholesome primates would simply disappear, and their our bodies have been by no means recovered by researchers. It is rather doable they, too, have been killed by the Western ‘riot’.

“With practically 200 people, together with greater than 30 grownup males, the Ngogo chimpanzee group exceeded the scale of different chimpanzee teams, probably straining the capability for relationship upkeep,” the analysis staff hypothesizes.

“Though an alpha male change alone doesn’t clarify why the Ngogo group cut up, it could have amplified tensions between the 2 clusters.”

James Brooks, from the German Primate Middle, who was not concerned within the analysis, says it’s too early to attract any agency conclusions about why this chimp group ruptured, or what which means for different teams and species, together with ourselves.

“However,” he writes in an accompanying perspective, the examine offers “essential data for… modeling the socioecological processes that underlie these occasions.”

People might share 98.8 p.c of our DNA with chimpanzees, however our genes are usually not our future. {Our relationships} with others can drive lethal divisions, however they will additionally foster cooperation and compassion.

“Relational dynamics might play a bigger causal position in human battle than typically assumed,” counsel Sandel and colleagues.

“In some instances, it could be within the small, day by day acts of reconciliation and reunion between people that we discover alternatives for peace.”

Deriving the TWFE Weights (Half 1)


We’re going to be, on this sequence, going gradual. The aim will probably be two issues. One, study the continual diff-in-diff paper by Callaway, Goodman-Bacon and Sant’Anna (CBS), conditionally accepted at AER. Two, I’m going to take a stab at constructing one thing that I can use once more — a bundle. Brantly Callaway already has an R bundle, so we are going to see what it’s we are able to pull off, however my sense is that if we are able to make the bundle do some issues that’s not already in that bundle (like calculate the TWFE weights, embody covariates, or who is aware of what else), then it’ll assist me as a result of I believe I have to personally make one thing if I’m going to grasp this paper. And I’m wanting, too, for some workouts that I believe will assist me deepen my expertise with Claude Code, and attempting to sketch out a bundle looks like a great one. As this bundle is for myself, it’s beta solely, and my objective is only for us to at the start study the paper, after which see if we are able to use Claude Code to assist me obtain that objective.

However at the moment goes to be fundamental. Our objective goes to solely be creating the structure for our saved native listing utilizing a wide range of new /expertise. Particularly, we will probably be utilizing the /beautiful_deck ability, the /split-pdf ability, the /tikz ability and the /referee2 ability. As not all of those expertise have been mentioned earlier than on right here (however which I take advantage of so much), I clarify what they every do, and supply the prompts as properly. We will probably be creating an exquisite deck of step one concerned within the CBS decomposition of the TWFE coefficient in cases with steady doses.

Thanks once more for supporting this substack, in addition to my e-book, Causal Inference: The Mixtape, my workshops at Mixtape Periods with Kyle Butts and others, and my podcast. Serving to folks achieve expertise and entry to utilized econometric instruments by a wide range of artistic efforts is form of my ardour. It’s a labor of affection. In case you aren’t a paying subscriber, take into account changing into one at the moment! I hold the worth as little as Substack lets me at $5/month and $50 for an annual subscription (and $250 for founding members). The Claude Code stuff will for some time proceed to be free at its launch, although which will change sooner or later since after 6 months, there are such a lot of sources. Mine will proceed to deal with sensible analysis functions or what I name “AI Brokers for Analysis Employees”. Thanks!

I’ve a idea. My idea is that nobody really needed to study the brand new diff-in-diff estimators (beneath differential timing) till Andrew Goodman-Bacon’s paper, in the end revealed within the 2021 Journal of Econometrics, confirmed in a really clear approach that the vanilla TWFE specification was biased. It was biased even with parallel developments.

My idea is that writ massive, most utilized folks don’t care about new estimators till they are often convincingly proven that there’s something incorrect with the estimator that they already use, and in the event that they may also be proven that it’s problematic even with the assumptions they thought have been enough. And so when Bacon’s paper got here out exhibiting that TWFE (thought then to really be a synonym for difference-in-differences, not an estimator) was biased, it actually shook folks.

Now you possibly can disagree with my idea, however that’s my working speculation, and I’m utilizing it to inspire this sequence. And right here is my conjecture. I don’t suppose folks actually, deep down, wish to study this new steady diff-in-diff paper. I believe many individuals are on the opposite aspect of the diff-in-diff Laffer curve. They wish to see much less diff-in-diff stuff; no more. And the one approach that they are going to voluntarily make an individual select to study one other diff-in-diff estimator is in the event you may help them perceive that the estimator of selection — TWFE — is biased. In any other case, we have now payments to pay, mouths to feed, miles to run, and courses to show.

Share Scott’s Mixtape Substack

So, the plan then to assist do that’s to review the TWFE decomposition that Callaway, Goodman-Bacon and Sant’Anna derive. I requested Bacon by textual content the opposite day may I simply name this paper CBS as a result of CGBS doesn’t roll off the tongue. He mentioned I may, as a result of everybody calls him Bacon anyway, so I’m calling it CBS. Let’s get began then.

So Pedro Sant’Anna introduced yesterday at Harvard and he famous that there are two ways in which econometricians have approached causal inference. The primary is what he calls “backwards engineering”. Backwards engineering is the place you kind of run a regression, and utilizing some instrument like Frisch-Waugh-Lovell crack open the regression coefficient and determine what causal estimand, if any, you simply calculated. Typically the weights are so bizarre and poorly behaved that you just didn’t in any respect. And that’s backwards engineering.

Thanks for studying Scott’s Mixtape Substack! This publish is public so be at liberty to share it.

Pedro prefers the second method which he calls “forwards engineering”. And ahead engineering is the place you state the causal estimand you have an interest in, you be aware the assumptions that you just suppose are life like in your information, you do a specific calculation that whenever you invoke these assumptions the calculation is that inhabitants estimand — or quite the imply of the sampling distribution is.

Nicely, we’re going to do each of those, however at the moment we’re going to do backwards engineering. And we’re doing it first due to what I mentioned in above — I believe folks should be taught what the coefficient they love means first, and in the event that they don’t like listening to what it’s, then they could really be prepared to sacrifice their time to take heed to a brand new one.

However we wish to use Claude Code to assist us right here, so let’s begin with the regression initially.

(Y_{i,t}= θ_t + η_i + β^{twfe} D_i·Post_t + v_{i,t})

After which we are going to be aware from the paper what the beta means. Listed here are the CBS weights.

Bleh, proper? That’s gnarly wanting. So that is the place Claude Code goes to assist us. What we’re going to do is actually write a bundle collectively that when invoked will really calculate these weights.

However to do it, we’re going to wish an software. Kyle Butts developed an software for our CodeChella so I’m going to make use of it. It’s by “Commerce Liberalization and Markup Dispersion: Proof from China’s WTO Accession” by Yi Lu and Lingui Yu, 2015 American Financial Journal: Utilized Economics. Right here’s what the paper is about.

Lu and Yu’s paper is about China’s 2001 WTO accession. This compelled industries with pre-WTO tariffs above 10% to chop them to the ceiling. Lu and Yu use the dimensions of that predicted tariff minimize as a steady “dose” to estimate, through an industry-level DiD on 3-digit SIC panels from 1998–2005, whether or not commerce liberalization diminished within-industry dispersion of agency markups (measured by the Theil index and 4 different dispersion statistics). And their reply was within the affirmative. Industries hit with bigger mandated tariff cuts noticed bigger declines in markup dispersion, which they interpret as commerce liberalization decreasing useful resource misallocation. In order that will probably be our software.

So the very first thing that I did was learn the paper so much. That’s over a number of years, however I encourage you to learn the paper. The paper follows the groups’ philosophy of forwards engineering, however Desk 1 will get into backwards engineering the TWFE coefficient like I mentioned, and whereas I perceive why you forwards engineer, I believe for studying functions when the world makes use of one estimator already, I believe it’s really extra pedagogically helpful to backwards engineer. So we are going to. However first, we are going to use my instrument /split-pdf and this immediate:

Please use /newproject in right here, transfer the pdf on this folder already into the readings or articles folder, then use /split-pdf on it. Write a abstract of every break up in markdown. After which write a abstract of the entire thing. Pay cautious consideration to exactly find out how to calculate the twfe weights in desk 1, additionally. That’s what we're going to deal with ourselves.

So, what I had accomplished was I created a brand new empty folder, I put the paper in there, after which I had Claude Code break up the paper into smaller pdfs, then write markdown summaries of every one, after which as soon as it was accomplished with that, write a markdown abstract of all of the markdowns. Then we are going to do the identical for the China-WTO article. Right here was my immediate once more utilizing /split-pdf.

Use /split-pdf on Lu-Yu, make summaries of every break up in markdown, then create one huge abstract markdown of these smaller splits. Make the objective to deeply perceive their TWFE estimation technique, and a deep understanding of dose and outcomes along with no matter you ordinarily do.

I copied all of these items now to my web site so you possibly can see them, each the manuscripts and each markdown summaries from /split-pdf. Right here they’re.

And now I’m going to conclude. What we at the moment are going to do is make a “stunning deck” utilizing my rhetoric of decks essay to information us, have my /referee2 ability to critique its total group, after which a brand new ability I created just lately, /tikz, to comb by and repair any Tikz associated compile errors. All of those might be discovered at my MixtapeTools repo, and you’ll both clone it domestically if you need, or you possibly can simply have Claude Code learn it in your aspect (or Codex — no matter). Let me briefly clarify what every does.

The rhetoric of decks essay is one thing I’ve labored on right here and there. However basically, it’s primarily based on the premise that decks have their very own rhetoric, Claude has been educated kind of on each deck each created (in addition to each different piece of writing), and that the tacit information concerned in making good, unhealthy, mediocre and nice decks can and has been extracted by the massive language mannequin. And the rhetoric idea is within the classical sense in keeping with Aristotle’s three ideas of rhetoric that are as follows:

  • Ethos (credibility): The speaker’s authority and trustworthiness, earned by demonstrated experience and trustworthy acknowledgment of uncertainty. In decks, it reveals up as methodology diagrams, citations, and brazenly naming the options you thought of which sign you’ve accomplished the work.

  • Pathos (emotion): Enchantment to the viewers’s emotions, values, and aspirations together with what they worry, hope for, or acknowledge from expertise. In decks, it means opening with an issue the viewers feels, validating their frustrations, and exhibiting what success appears to be like like, although pathos with out logos collapses into demagoguery.

  • Logos (logic): Reasoned argument grounded in proof, construction, and acknowledgment of counterarguments. Once more, in decks, it seems as information visualizations, comparability tables, and a transparent movement from downside to resolution, however logos with out pathos is only a lecture that produces disengagement.

And for this train, I lastly bought round to turning my rhetoric of decks essay right into a ability referred to as /beautiful_deck. You’ll be able to name it now, and if you wish to learn extra about it, simply go right here to my /expertise listing. The default is it is going to create an exquisite deck in LaTeX’s beamer bundle following my explanations of what I’m going for in decks — information visualization and quantification, stunning slides, stunning tables, stunning figures, not a wall of phrases, sentences or equations, minimizing cognitive density of slides, max one thought per slide (two tops), utilizing Tikz for graphics and/or .png from software program packages like R, python, Stata, instinct, narrative, and at last technically rigorous exposition. However I’ve made it so you too can point out you need it in a special format like Quarto, markdown, and so on. Your name. One of many issues that /beautiful_deck does is it additionally checks for compile errors from overfull, field, and so on., and makes an effort to eradicate them, irrespective of how beauty they’re.

Begin writing at the moment. Use the button beneath to create a Substack of your personal

Begin a Substack

As we’re going to make an exquisite deck in beamer utilizing the /beautiful_deck ability, it is going to be by default utilizing Tikz, the highly effective and graphics bundle with almost impenetrable and really sophisticated (to me anyway) LaTeX syntax. Yow will discover an instance of it right here.

Nicely, the default within the /beautiful_deck ability is to test for all compile errors the place the content material of the slide is mainly spilling off the slide’s margins. That is when phrases go beneath the top of the slide and turn out to be unreadable, as an illustration.

However not all visible compile issues are caught inside the /beautiful_deck ability itself. As an illustration, the labels on graphics routinely, when purely automated, will intervene with different objects. Phrases, as an illustration, will probably be interfering with bins or strains. Issues will cross each other. And that is most likely associated to the truth that massive language fashions have poor spatial reasoning.

So, the /tikz ability is used to confirm that the placement of phrases, equations, and different labels aren’t blocks or crossing different objects. One of many issues /tikz makes use of to appropriate for this within the decks is that it makes use of Bézier curves that are parametric curves outlined by management factors, and my /tikz ability makes use of depth formulation on them to detect and repair arrow/label collisions in order that they don’t occur.

It’s not excellent. However, it will possibly assist. And I strongly encourage you to test your decks intently, and in the event you nonetheless see belongings you don’t like, do away with them. At the moment, we must always not tolerate any beauty errors like the placement of labels. Our objective is henceforth to make stunning decks and delightful decks have stunning footage, and delightful decks shouldn’t have errors.

And the final ability is my /referee2 ability which writes referee reviews critiquing code and decks. /referee2 is my adversarial audit ability with two modes: a code mode that performs a full five-audit cross-language replication protocol on empirical pipelines, and a deck mode that opinions Beamer displays for rhetorical high quality, visible cleanliness, and compile hygiene towards the Rhetoric of Decks ideas.

In deck mode it systematically checks each slide for titles-as-assertions, one-idea-per-slide, no wall of sentences, minimized cognitive density and stability throughout the deck, appropriate TikZ coordinate placement (utilizing the identical measurement guidelines as /tikz), and nil Overfull/Underfull/vbox/hbox warnings within the compile log. When full, it information a proper slide-by-slide report with settle for / minor-revision / major-revision verdicts. It’s meant to run in a recent terminal by a Claude occasion that has by no means seen the deck, so the evaluation is structurally unbiased from whoever constructed it. It is also used to audit code, although. For now, it’s not actually arrange for paper evaluation although I’m certain you need to use it for that in the event you needed (and I’ve).

And now we’re prepared. We’re going to ask Claude Code to make an exquisite deck that explains to make use of the TWFE decomposition in CBS. The objective is to take an individual who’s unfamiliar with their decomposition from understanding completely zero to completely one thing.

However our objective is extraordinarily slender. Since TWFE all the time constructs its coefficients utilizing this method, which is numerically the identical because the sum of squared residuals method which estimates the parameters a special approach, we are going to not be centered on their causality interpretation simply but. Our objective is solely to know the algebra of the decomposition divorced from causal inference and diff-in-diff totally. So right here it goes. It’s lengthy, however that’s primarily person error. I are inclined to over clarify issues to Claude, which admittedly makes use of a variety of tokens, so be at liberty to alter this if you need.

Please make an exquisite deck utilizing the rhetoric decks essay and /beautiful_deck of the CBS paper we summarized. Use the markdowns solely. And you'll apply it to the AEJ WTO paper that we additionally marked down. However at the moment’s objective on this deck is extraordinarily slender. I would like you to deal with the TWFE estimation, with a steady dose in -diff-in-diff, exhibiting the equation, and its historic interpretation. Clarify the context by which it's used within the AEJ paper. Then I would like you to ONLY deal with the algebraic decomposition of the method that's in Desk 1 of the CBS paper. There are a number of decompsoitions related to a number of various things so slowly take us by each however accomplish that utilizing the rhetoric of decks utilized toa. group of people who find themselves needing to go slowly and who discover the notation complicated at first look. So you need to be heavy on the applying first, the instinct second, all the time inside narrative and Aristotle’s rhetoric ideas, the precise information software (so produce R code or python code or Stata code that does this in replicable code), .tex information from that evaluation, heavy on Tikz graphics and quantification, use .png, and so forth. I would like the viewers to go from understanding zero concerning the CBS decomposition to understanding it on the finish. However no causal inference. Solely algebraic calculation of the weighting schemes concerned, and the interpretation of every enter utilizing shading, highlights, little brackets beneath equations, constructing block graphics, and so forth. Our objective in that is PURELY to know the weighting invlved in TWFE beneath these numerous measurements contained in Desk 1 solely. And remember-- magnificence first!

After it ran, I requested it to then use /tikz to repair labeling, and so on., after which /referee2 to critique it. And as soon as these have been accomplished, I advised Claude to do the whole lot /referee2 mentioned to do. This isn’t instantaneous, and it’ll spend about 20k to 25k tokens more than likely all mentioned and accomplished. So not low-cost, however on the similar time, however on the similar time, it wouldn’t get you on the Meta chief board which was a contest they ran to see who may use essentially the most tokens. The winner basically price the corporate over one million {dollars} over 30 days by utilizing one thing like 1 billion tokens.

Virtually definitely there’s a extra environment friendly workflow and I’m going to spend time someday attempting to see what I can do to do this, however you get the gist. In case you ideas, although, please go away them on methods you may enhance, and I’ll evaluation them and have a dialog with my Claude to see if I ought to do it. Right here is the ultimate product.

I’m going to, for at the moment, simply publish what I’ve although I think I’ll tinker extra with the deck later. I determine seeing the preliminary output, although, might be okay for the substack, as who is aware of — possibly the preliminary will land. Although I have a tendency to wish issues persistently reframed in a approach that matches how my mind works, and I sometimes go spherical and spherical with Claude on deck manufacturing till it’s precisely how I prefer it. So I could have to do this after I begin studying it.

That’s it for at the moment. This was so much. Within the subsequent entry, we are going to begin unpacking the content material from the deck however within the meantime, I encourage you to experiment with all of this in your finish. That approach you will get caught up in your personal time. Once we return, we are going to begin attempting to decipher the decomposition method. You might be inspired to learn the paper intently, however we will probably be narrowly centered on simply the decomposition method of the TWFE estimator within the steady dose diff-in-diff case.

Thanks once more for studying. This substack is a labor of affection, and in the meanwhile, I’m going to proceed to make the explicitly Claude Code posts initially free so that every one readers can study a bit how I take advantage of it. However I do encourage you to share this substack with others, notably utilized researchers desirous to study Claude Code within the context of studying one thing they’re primarily all for — utilized statistics, causal inference, information science, program analysis and econometrics for their very own analysis functions. And in the event you aren’t already a paying subscriber, take into account changing into one!

Choosing a Date Vary in CSS


A date vary selector lets customers choose a timeframe between a begin and finish date, which is helpful in reserving journeys, sorting information by date blocks, choosing time slots, and planning schedules.

Instance pulled from Airbnb

I’m going to point out you an instance the place, though JavaScript is concerned, the majority of the work is dealt with by the “n of selector(s)” syntax of the CSS :nth-child selector, making it straightforward to construct the vary choice.

The “n of selector” syntax

This syntax of the :nth-child selector filters parts by a given selector first amongst all of the youngster parts, earlier than choosing them by a counting order.

The reclamation of land...


The primary reclamations might be traced...


By 1996, a complete of...

.accent {
  coloration: pink;
}
.accent:nth-child(2) {
  font-weight: daring; /* doesn't work */
}
:nth-child(2 of .accent){
  text-decoration: underline;
}

There are two .accent-ed paragraphs with pink textual content. As we attempt to goal the second accented paragraph, .accent:nth-child(2) fails to pick it as a result of it’s looking for an .accent aspect that’s the second youngster of its guardian.

Whereas, :nth-child(2 of .accent) succeeds in choosing and styling the second accented paragraph as a result of it’s solely searching for the second aspect among the many **.accent** parts quite than the second of the entire kids.

The Format

Shifting onto our most important instance, let’s put collectively a month structure. It solely takes just a few strains of CSS.

#calendar {
  show: grid;
  grid-template-columns: repeat(7, 1fr); /* 7 for no. of days in per week */
}

Select Solely Two Dates

Now's once we attain for JavaScript since we are able to’t examine/uncheck a management in CSS. However even right here the “n of selector” syntax might be very helpful.

After we choose two dates to create a spread, clicking on a 3rd date will replace the vary and take away one of many earlier dates.

You may arrange the vary re-adjustment logic in any method you want. I’m utilizing this method: If the third date is both earlier or later than the final return date, it turns into the new return date, and the outdated one is unselected. If the third date is sooner than the final onward date, it turns into the brand new onward date, and the outdated one is unselected.

const CAL = doc.getElementById('calendar');
const DT = Array.from(CAL.getElementsByClassName('date')); 

CAL.addEventListener('change', e => {
  if (!CAL.querySelector(':checked')) return;
  
  /* When there are two checked containers, calendar will get 'isRangeSelected' class  */
  CAL.className = CAL.querySelector(':nth-child(2 of :has(:checked))') ? 'isRangeSelected':'';

  /* When there are three checked containers */
  if (CAL.querySelector(':nth-child(3 of :has(:checked))')) {

    change (DT.indexOf(e.goal.parentElement)) {

      /* If the newly checked date is first among the many checked ones, 
          the second checked is unchecked. Onward date moved earlier. */
      case DT.indexOf(CAL.querySelector(':nth-child(1 of :has(:checked))')):
      CAL.querySelector(':nth-child(2 of :has(:checked)) enter').checked = 0; 
      break;

      /* If the newly checked date is second among the many checked ones, 
          the third checked is unchecked. Return date moved earlier. */
      case DT.indexOf(CAL.querySelector(':nth-child(2 of :has(:checked))')):
      CAL.querySelector(':nth-child(3 of :has(:checked)) enter').checked = 0; 
      break;

      /* If the newly checked date is third among the many checked ones, 
          the second checked is unchecked. Return date moved later. */
      case DT.indexOf(CAL.querySelector(':nth-child(3 of :has(:checked))')):
      CAL.querySelector(':nth-child(2 of :has(:checked)) enter').checked = 0; 
      break;

    }
  }
});

First, we get the index of the present checked date (DT.indexOf(e.goal.parentElement)), then we see if that’s the identical as the primary checked amongst all of the checked ones (:nth-child(1 of :has(:checked))), second (:nth-child(2 of :has(:checked))), or third (:nth-child(3 of :has(:checked))). Provided that, we then uncheck the related field to revise the date vary.

You’ll discover that through the use of the “n of selector” syntax, focusing on the :checked field we would like by its place amongst all checked ones is made a lot easier — as a substitute of indexing via an inventory of checked dates in JavaScript for this, we are able to instantly choose it.

Styling the vary is even simpler than this.

Styling the Vary

/* When two dates are chosen */
.isRangeSelected { 
  /* Dates following the primary however not the second of chosen */
  :nth-child(1 of :has(:checked)) ~ :not(:nth-child(2 of :has(:checked)) ~ .date) {
    /* Vary coloration */
    background-color: rgb(228 239 253); 
  }
}

When there are two dates chosen, the dates between the primary (1 of :has(:checked)) and second (2 of :has(:checked)) are coloured pale blue, creating a visible vary for that block of dates within the month.

A calendar month layout with the dates 9-29 selected. 9 and 19 have a dark blue background and the dates between are light blue.

The colour is asserted inside a compound selector that selects dates (.date) following the to start with checked date (:nth-child(1 of :has(:checked))), however not the second of all checked date (:not(:nth-child(2 of :has(:checked))).

Right here’s the complete instance as soon as once more:

Cisco Celebrates The Sensible Trade Industrial Transformation Award Winners


Sensible Trade, a number one analysis and media agency overlaying a wide selection of business sectors, simply launched its 2026 Sensible Trade Industrial Transformation Awards (ITAs), with Cisco serving as a proud sponsor. The 9 honorees—Keurig Dr Pepper (KDP), Rivian, The Walt Disney Firm, Alabama DOT, Arkansas DOT, Texas DOT, Duke Power, Nationwide Grid, and NorthWestern Power —span manufacturing, transportation, and utilities. Their award-winning initiatives fluctuate from reversible visitors lanes to grid modernization to amusement-park monitoring. However right here’s what caught our consideration: beneath these floor variations are three shared patterns.

At Rivian, the IT, OT, and manufacturing engineering groups constructed standardized community architectures that included beforehand remoted operational networks. Now the electrical car producer has end-to-end visibility throughout manufacturing tools, automation methods, and analytics platforms, contributing to 99.99% community uptime and nil unplanned community downtime. “The community—as soon as our weakest hyperlink—is now essentially the most dependable and trusted part of Rivian’s manufacturing ecosystem,” mentioned Rohini Mor, Rivian’s senior supervisor of community engineering.

Reliability additionally rose at Duke Power. After mergers left the corporate with disjointed networks, the utility’s telecom crew labored with the transmission, distribution, and gasoline groups emigrate grid automation management and communications throughout services and circuits. “Transitioning to IP and updating the community infrastructure, operational headend functions, and distant tools… contributed to improved community reliability above 99.7%,” reported Bryan Fullenkamp, IT community architect. Higher community up time can have an effect on grid uptime, actually holding the lights on.

Keurig Dr Pepper (KDP) re-imagined its manufacturing community basis to extend visibility and resilience. “Shut collaboration between manufacturing engineering, IT, and our strategic companions supplied a way of shared possession, [making the network] a resilient, compliant spine for sensible manufacturing development,” mentioned Arno Thijssen, course of and automation engineer at KDP.

The 2026 ITA winners additionally showcase the significance of OT and IT collaboration, particularly for safety and visibility. Nationwide Grid was acknowledged for its initiative to digitize and develop the grid to organize for excessive climate circumstances and rising cyberattacks. “Eradicating silos inside OT and IT groups and getting the groups to interact and belief the collaboration course of… is the largest problem,” famous Adriano Antiquera, Nationwide Grid’s platform director.

Disney fosters IT/OT collaboration by ensuring that each groups are represented in each design, vendor, and structure dialogue. The corporate invested in joint coaching, together with Cisco certifications for OT engineers, and ISA/ICS safety coaching for IT workers. “Instantly, groups might see challenges from the opposite perspective, which accelerated collaboration and problem-solving,” mentioned Dan Mastropietro, a technical fellow with Disney’s international community engineering and choices.

Arkansas DOT introduced its IT and OT groups collectively to construct a reversible lane to alleviate congestion on a closely trafficked bridge. The challenge required a fault-tolerant community spine for OT methods like real-time lane management, automated signage updates, and incident response coordination. “This structure fostered real-time information change, permitting IT and OT groups to collaborate extra successfully,” mentioned Jeremy Hill, community administrator for the Arkansas DOT.
