🌟 What’s New in Stata 19.5

1. Power Analysis for Logistic Regression

Plan biomedical studies with precision using the power logistic command. This new feature lets you calculate sample size, effect size, or statistical power for binary outcomes (e.g., treatment vs. placebo, disease vs. no disease). Tabular and graphical outputs make study design easier for researchers and clinical trialists.

2. Enhanced Causal Inference Tools

Causal research is central to medical science. Stata 19.5 introduces Conditional Average Treatment Effects (CATE) and Local Average Treatment Effects (LATE), expanding the possibilities for robust treatment effect estimation in observational studies. These tools help ensure your findings are scientifically valid and ready for publication.

3. High-Dimensional Fixed Effects & Correlated Random Effects

Analyze panel and longitudinal data more effectively with High-Dimensional Fixed Effects (HDFE) and Correlated Random Effects (CRE). These models allow researchers to control for unobserved heterogeneity, making large-scale health studies and longitudinal biomedical datasets more accurate.

4. Bayesian Modeling Enhancements

Stata 19.5 takes Bayesian inference to a new level. It now supports Bayesian quantile regression, Bayesian variable selection, and new prior distributions like Half-Cauchy and Rayleigh. Posterior prediction has also been improved, making Bayesian methods more flexible and efficient for biomedical research.

5. Survival & Time-to-Event Models

For clinical and biomedical research, survival analysis is critical. Stata 19.5 introduces marginal Cox models for interval-censored and multiple-event data. The survival plots have been enhanced with more flexible options, improved at-risk tables, and graphical customizations.

6. Machine Learning with H2O Integration

Harness the power of machine learning inside Stata with H2O ensemble tree methods. These models are perfect for predictive medicine, diagnostics, and biomedical risk scoring, providing scalable solutions for large datasets.

7. Graphics, Visualization & Reporting Improvements

• New heat maps for biomedical data visualization.

• Bar graphs with confidence intervals for clearer comparisons.

• Extended color schemes and graphing controls.

• Smarter tables and reporting tools for easier export to Word, Excel, and PDF.

8. Do-File Editor & Workflow Productivity

• Autocompletion, code folding, and customizable templates.

• A history ribbon to track changes to scripts.

• Temporary bookmarks for navigating large analysis scripts.

• Enhanced PyStata integration with Python for streamlined workflows.
