Description: Fits models for Rasch Measurement Theory, whose defining
    measurement properties include sufficiency and invariance. Available
    models include the dichotomous Rasch, partial credit, rating scale,
    many-facet, extended frame of reference and explanatory models.
    Explanatory modelling supports predictors at the item and threshold
    levels. Comparative judgement models are available for dichotomous and
    ordered pairwise responses, with support for extended frames of reference
    and explanatory predictors. Functions support estimation and examination
    of model fit, targeting, reliability, dimensionality, local dependence,
    differential item functioning, equating and simulation. A graphical
    interface for fitting models and examining results is provided through an
    interactive 'shiny' application.
