Stata — 18 |link|

Model uncertainty is a silent killer of replicability. Stata 18’s new bmaregress command addresses this by averaging over thousands of potential models rather than choosing one. It computes posterior probabilities for each predictor, giving you a robust understanding of variable importance.

This brings Stata in line with RStudio Projects and Jupyter Notebook workflows, dramatically reducing setup time and errors.

The new post-estimation command estat trendplots allows you to visually test the parallel trends assumption—a critical diagnostic that previously required complex user-written commands.

Stata 18 is available in four flavors:

Stata 18 remains one of the best-documented software packages in the world: New reporting features | New in Stata 18

Stata 18, released on April 25, 2023, represents a significant evolution of the statistical software package, introducing over 30 major new features across causal inference, Bayesian analysis, and reporting. This version marks the transition of Stata into a more continuous update cycle through the introduction of , a new delivery model that provides features as soon as they are ready rather than waiting for a major version release.
