Latent class analysis (LCA) Discover and understand the unobserved groupings in your data. Use LCA's model-based classification to find out how many groups you have, who is in those groups, and what makes those groups distinct.

Linearized DSGEs Write your model in simple algebraic form. Stata does the rest: solve model, estimate parameters, estimate policy and transition matrices (with CIs), estimate and graph IRFs, and perform forecasts.

Finite mixture models (FMMs) 17 estimators and combinations Continuous, binary, count, ordinal, categorical, censored, and truncated outcomes Survival outcomes

                  where you are


                                  matters.

Interval-censored survival models Fit any of Stata's six parametric survival models to interval-censored data. All the usual survival features are supported: stratified estimation, robust and clustered SEs, survey data, graphs, and more.

Nonlinear multilevel mixed-effects models When ... your science ... says ... your model ... is ... nonlinear in its parameters

Nonparametric regression When you know something matters. But have no idea how.

Bayesian multilevel models Small number of groups? Many hierarchical levels? Prefer making probability statements? Consider Bayesian multilevel modeling.

Threshold regression Your time-series regression may change parameters at some point in time or at multiple points in time. The activity of foraging animals might follow a completely different pattern at temperatures above some threshold. You may not know the value of that threshold. Finding such thresholds and estimating the parameters within the regimes is what threshold regression does.

Panel-data tobit with random coefficients Stata has long had estimators for random effects (random intercepts) in panel data.

Search, browse, and import FRED data The St. Louis Federal Reserve makes available over 470,000 U.S. and international economic and financial time series. You can now easily search, browse, and import these data.

Tests for multiple breaks in time series Cumulative sum (CUSUM) test for parameter stability CUSUM of recursive residuals CUSUM of OLS residuals Plots with CIs

Multiple-group generalized SEM Generalized SEM now supports multiple-group analysis. Easily specify groups and test parameter invariance across groups. GSEM models include continuous, binary, ordinal, count, categorical, and even survival outcomes multilevel models
