StataNow 19.5: Feature Highlights
We’re excited to introduce the new features in StataNow 19.5.
1) Power Analysis for Logistic Regression (May 21, 2025 update)
Design binary-outcome studies with confidence: power logistic computes required sample size, power, or effect size for a coefficient of interest, with tabular/graph outputs and support for additional nuisance covariates.

2) Local Average Treatment Effects (LATE) (August 13, 2025 update)
Estimate LATE for the population of compliers using lateffects. Choose among kappa-weighted and covariate-balancing estimators or IPWRA; built-in diagnostics help assess overlap and balance.

3) More VCE Options for Linear Models (August 13, 2025 update)
Stata’s most used linear regression commands now support a broader set of variance–covariance (VCE) options:
- HAC and Driscoll–Kraay SEs,
- HC2/HC3 (with clustering),
- Hansen-style corrections,
- multiway clustering,
- unstructured time-covariances in panel GLS.
