New features

Stata 19 introduces a range of new features that enhance data analysis, visualisation, and efficiency. Here are some of the most significant updates:

• Machine learning via H2O: Ensemble decision trees — Employ machine learning to uncover insights from the data when traditional statistical models fall short. Use ensemble decision trees—gradient boosting machine (GBM) and random forest—to perform regression or classification.
• Conditional average treatment effects (CATE) — Go beyond estimating overall treatment effects in your causal analysis to estimating individualised and group-specific ones. Compare different interventions and policies. Explore treatment-effects heterogeneity.
• High-dimensional fixed effects (HDFE) — Absorb not just one but multiple high-dimensional categorical variables in your linear, fixed-effects linear, and instrumental-variables linear models, and enjoy remarkable speed gains!
• Latent class model-comparison statistics — Easily compare latent class models with varying numbers of latent classes. Construct and export publication-quality tables comparing models.
• Do-file editor enhancements — The Do-file Editor now includes autocompletion, customisable templates, code folding enhancements, and better navigation tools, making coding in Stata more efficient than ever.
• Advanced graphics features — Enjoy exciting new graphical features such as heat maps, spike and capped-spike range plots, bar graphs with CIs, and more!
• Stata in French — All of Stata's interface—all menus and all dialogs—is now available in French, joining English, Chinese, Japanese, Korean, Spanish, and Swedish.
