lcmm-package: Estimation of extended mixed models using latent classes and...

Description Details Author(s) References


Functions for the estimation of latent class mixed models (LCMM), joint latent class mixed models (JLCM) and mixed models for curvilinear and ordinal univariate and multivariate longitudinal outcomes (with or without latent classes of trajectory). All the models are estimated in a maximum likelihood framework using an iterative algorithm. The package also provides various post fit functions.
