StataNow 19.5: New Feature Highlights
We are pleased to introduce the latest features available in StataNow 19.5.
1) Psychometric Meta-Analysis (January 28, 2026 update)
Stata now supports psychometric meta-analysis of correlations with the new meta psycorr command. The method corrects for measurement error and includes adjustments for direct and indirect range restriction, dichotomization, and small-sample bias. Analyses can be seamlessly extended using Stata’s meta suite, including forest plots and subgroup analyses.

2) Moderating Effects in Heterogeneous DID Models (January 28, 2026 update)
Following a heterogeneous difference-in-differences analysis with two-way fixed effects, moderating effects of covariates can now be examined. The new postestimation command estat moderation shows how cohort- and time-varying ATETs change with covariates, providing deeper insight into treatment effect heterogeneity.
