Implements the Linear Logistic Test Model (LLTM;\nFischer (1973) ), the\nMulticomponent Latent Trait Model for Diagnosis (MLTM-D;\nEmbretson and Yang (2013) ), and\nthe Generalized Multicomponent Latent Trait Model for Diagnosis\n(GMLTM-D; Ramirez et al. (2024)\n), including a variant with\ncorrelated latent components. All models are estimated via\nHamiltonian Monte Carlo using 'Stan' through the 'rstan'\ninterface. Includes tools for prior predictive checks (Gelman\net al., 2020), model validation, conditional reliability\nestimation, examinee mastery classification following Embretson\n(2019) , and individual\ndiagnostic reports at the rule and component level.
