Stata Features

Stata includes a wide range of features to meet all your data science needs. Some of the key features are listed below:

What’s new in the Stata 18 edition

Stata 18 presents a wide range of new features! Here is a zoom on some of the main features:

Bayesian model averaging (BMA)

Uncertain which predictors to use in your regression? Model averaging can help! Use this feature to account for model uncertainty in your analysis, explore influential models and predictors, get better predictions, and more.

Causal mediation analysis

This new feature allows you to evaluate how the treatment affects the outcome. You can also estimate direct, indirect and total effects. You can fit models for continuous, binary and count outcomes as well as mediators. The mediate command is very flexible and supports 24 combinations of models.

Heterogeneous difference in differences (DID)

Estimate treatment effects that vary over groups and time. You can fit models for repeated cross-sectional or panel data. You can also visualize effects and aggregate them within group, time, or exposure to treatment.

Relative excess risk due to interaction (RERI)

Use RERI to determine how do exposures interact to increase risk? You can fit logistic, binomial, Poisson, Cox, and other models. You can also estimate relative excess risk due to interaction (RERI), attributable proportion and the synergy index.

Robust inference for linear models

Stata 18 offers new ways to obtain standard errors and confidence intervals for linear models fit with regress, aref and xtreg, fe. You can estimate cluster-robust standard errors, with few clusters, unbalanced clusters or multiple clustering variables. You can now add the vce(hc2 clustvar) option to obtain HC2 cluster-robust standard errors. Also use the wild cluster bootstrap for robust p-values and confidence intervals.

Stata 18 offers other major new features among which:

• Tables of descriptive statistics
• Group sequential designs
• Multilevel meta-analysis
• Meta-analysis for prevalence
• Wild cluster bootstrap
• Local projections for IRFs
• Flexible demand system models
• TVCs with interval-censored Cox model
• Lasso for Cox model
• IV quantile regression
• IV fractional probit model
• Alias variables across frames
• Data Editor enhancements
• Do-file Editor enhancements
• All-new graph style

This new version also includes the following new features / optimizations:

• Corrected and consistent AIC
• Model selection for ARIMA and ARFIMA
• GOF plots for survival models
• New spline functions
• Graph colors by variable
• Create, load, and save sets of frames
• Boost-based regular expressions
• Vectorized numerical integration
• New reporting features in putdocx, putexcel, and putpdf
