Here are the highlights of what’s new:
- Structural equation modeling, a.k.a. SEM. If you don’t know what SEM is, go here.
- Chained equations and more in Multiple Imputation.
- Contour plots.
- Excel import/export.
- New interface.
- Contrasts, Pairwise comparisons, and Margins plots.
- ROC analysis
- Multilevel models with survey data
- UCM (Unobserved Components Models)
- Multivariate GARCH
- Parametric spectral density estimation
- Time-series filters
- Business Calendars

- Automatic Memory Management. (You never have to set memory again, and never again will you be told that there is no room because you set too little.)
- Installation Qualification (IQ)
- Stata/MP, more estimators, more cores, …
There are other things that are new, too. Things like functions for Tukey’s Studentized range and Dunnett’s multiple range, baseline odds for logistic regression, truncated count-data regressions, probability predictions, robust and cluster-robust SEs for fixed-effects Poisson regression, and the like under General Statistics. Or under Survey Data, support for SEM, bootstrap and successive difference replicate (SDR) weights, goodness of fit after binary models, coefficient of variation, and more. Or under Panel Data, probability predictions, multiple imputation support, and more. Or under Survival Data, a goodness-of-fit statistic that is robust to censoring. Or PDF export of results and graphs.
We could go on, but you get the idea. We think Stata 12 is worth a look.
