Description: eRm fits Rasch models (RM), linear logistic test models
        (LLTM), rating scale model (RSM), linear rating scale models
        (LRSM), partial credit models (PCM), and linear partial credit
        models (LPCM). Missing values are allowed in the data matrix.
        Additional features are the ML estimation of the person
        parameters, Andersen's LR-test, item-specific Wald test,
        Martin-Loef-Test, nonparametric Monte-Carlo Tests,
        itemfit and personfit statistics including infit and outfit
        measures, various ICC and related plots, automated stepwise
        item elimination, simulation module for various binary data
        matrices. An eRm platform is provided at R-forge (see URL).
