Stata 18: !!top!!

Stata 18, released in April 2023, is a major update that emphasizes reproducible research, customizable reporting, and advanced causal inference. This version introduces several powerful commands and graphical improvements designed to streamline the workflow for researchers in economics, medicine, and social sciences. Key Feature Highlights

For new buyers, do not purchase Stata 17. Stata 18 is the more future-proof, feature-rich, and well-optimized version. StataCorp has clearly listened to its user community—especially regarding Python and modern DiD estimators. Stata 18

5. Reporting and Reproducibility

The push for reproducible research has led to significant improvements in Stata 18’s reporting toolset. Stata 18, released in April 2023, is a

Panel/Longitudinal Data

  • Dynamic Panel Models with xtdpdgmm (GMM estimators for linear dynamic panel data).
  • Fractional outcome models for panel data (xtfereg).

Building on the "Credibility Revolution" in econometrics, Stata 18 adds new tools for Difference-in-Differences (DID). Specifically, it now handles heterogeneous treatment effects. When different groups are treated at different times (staggered adoption), traditional TWFE (Two-Way Fixed Effects) models can be biased. Stata 18’s new commands provide robust estimators to handle these complex causal scenarios. All-New Meta-Analysis Features
