Description: Provides Bayesian estimation of Item Response Theory
        models that decompose item difficulty into cognitive operations
        or rules. Implements the Linear Logistic Test Model (LLTM;
        Fischer (1973) <doi:10.1016/0001-6918(73)90003-6>), the
        Multicomponent Latent Trait Model for Diagnosis (MLTM-D;
        Embretson and Yang (2013) <doi:10.1007/s11336-012-9296-y>), and
        the Generalized Multicomponent Latent Trait Model for Diagnosis
        (GMLTM-D; Ramirez et al. (2024)
        <doi:10.3390/jintelligence12070067>). All models are estimated
        via Hamiltonian Monte Carlo using 'Stan' through the 'rstan'
        interface. Includes tools for model validation, reliability
        estimation, and visualization of item characteristic curves.
        Supports user-defined prior distributions for all model
        parameters.
