%description
Estimate confirmatory latent class models for a variety of item response
types that are encountered in the clinical field. One or two timepoints
are supported. Latent regression estimation can be performed, allowing for
comparisons of longitudinal latent class assignments (e.g., treatment
success/failure) across observed groups (e.g., treatment arms in clinical
trials). Fit statistics C2 (a limited-information goodness-of-fit
statistic), Akaike Information Criterion (AIC), and Bayesian Information
Criterion (BIC) are available as well. Methods are described in
Iaconangelo (2026) <doi:10.5281/zenodo.22663151>.
