The package includes marginal and joint maximum likelihood
estimation of uni- and multidimensional item response models
(Rasch,  2PL, 3PL, Generalized Partial Credit, Multi Facets,
Nominal Item Response, Structured Latent Class Analysis,
Mixture Distribution IRT Models, Located Latent Class Models,
Cognitive Diagnostic Models), fit statistics and person parameter estimation.
