Muthen & Muthen

The Mplus Base Program and Combination Add-On contains all of the features of the Mplus Base Program and the Mixture and Multilevel Add-Ons. In addition, it includes models that handle both clustered data and latent classes in the same model, for example, two-level latent class analysis and multilevel growth mixture modeling. Other special features include missing data estimation, sampling weights, latent variable interactions and non-linear factor analysis using maximum likelihood, random slopes, individually-varying times of observation, non-linear parameter constraints, maximum likelihood estimation for all outcomes types, Monte Carlo simulation facilities, and a post-processing graphics module.
