For binary or fractional outcomes (like proportions) with endogenous regressors, Stata 18 provides a specialized instrumental-variables fractional probit estimator. 2. Unprecedented Speed with High-Dimensional Data
Meta-analysis is no longer just for medical trials; it’s becoming common in social sciences. Stata 18 expands its exclusive meta-analysis suite to include:
A %help magic allows users to view Stata help files directly in a web browser from within Python. New features in Stata 18 stata 18 exclusive
These new commands allow for the estimation of heterogeneous difference-in-differences (DID) effects. Researchers can now analyze treatment effects that change over time or vary across individuals, a crucial requirement for modern policy evaluation.
