We simply launched one other replace to StataNow. Make certain your copy of StataNow is updated so that you’ve the newest options, together with the next:
Import information from parquet recordsdata. Knowledge are more and more saved and distributed in Parquet format. Now you can use the import parquet command to simply import Parquet information into Stata. Most Parquet compression strategies and information sorts are supported.
Causal mediation evaluation with two mediators. The mediate command now lets you match causal mediation fashions with two mediators, whether or not these mediators are sequential or parallel. Decompose the whole impact of a remedy on an end result into pure direct and oblique results. You can too estimate managed direct results and carry out sensitivity evaluation for sequential mediation.
Compute quantiles in Mata. The brand new Mata quantile() perform computes quantiles. You’ll be able to select from 3 discontinuous strategies and 11 steady strategies for calculating quantiles.
We’ve additionally added new options which might be out there to everybody with Stata 19 and StataNow 19.
Postestimation instruments for H2O machine studying. After utilizing the h2oml instructions to carry out random forest or gradient boosting machine, you should utilize the brand new h2omlgraph permimp command to graph permutation variable significance and establish influential predictors. As well as, diagnostic plots are actually out there after gradient boosting regression and random forest regression. The brand new h2omlgraph rvfplot command graphs the residuals versus fitted values, and the brand new h2omlgraph rvpplot command graphs residuals versus a predictor.
Transfer information between Stata and Python NumPy arrays or pandas DataFrames. The Stata–Python API now contains capabilities for simply transferring information between NumPy arrays and Stata datasets, frames, Mata matrices, and Stata matrices. New capabilities are additionally out there for transferring information between pandas DataFrames and Stata datasets and frames.
Therapy-effect aggregation weights. Once you want to combination common remedy results on the handled after heterogeneous treatment-effect estimation, estat aggregation now lets you choose from aggregation weights which might be fixed inside cohorts or that change throughout time intervals and cohorts.
For extra options of StataNow 19 and Stata 19, see https://www.stata.com/new-in-stata/options/.
You’ll be able to kind replace all in your copy of StataNow or Stata 19 to get entry to those version-specific updates.
