diffaitbeta

Estimation of group-based trajectory models, including finite mixture models for longitudinal data,
supporting censored normal, zero-inflated Poisson, logit, and beta distributions,
using expectation-maximization and quasi-Newton methods, with tools for model selection,
diagnostics, and visualization of latent trajectory groups,
