Description: Analysis of items and persons in data. To identify and
        remove person misfit in polytomous item-response data using
        either 'mokken' or a graded response model (GRM, via 'mirt').
        Provides automatic thresholds, visual diagnostics (2D/3D), and
        export utilities. Methods build on Mokken scaling as in Mokken
        (1971, ISBN:9789027968821) and on the graded response model of
        Samejima (1969) <doi:10.1007/BF03372160>.
