Description: Several person-fit statistics (PFSs; Meijer and Sijtsma,
        2001, <doi:10.1177/01466210122031957>) are offered. These
        statistics allow assessing whether individual response patterns
        to tests or questionnaires are (im)plausible given the other
        respondents in the sample or given a specified item response
        theory model. Some PFSs apply to dichotomous data, such as the
        likelihood-based PFSs (lz, lz*) and the group-based PFSs
        (personal biserial correlation, caution index, (normed) number
        of Guttman errors, agreement/disagreement/dependability
        statistics, U3, ZU3, NCI, Ht). PFSs suitable to polytomous data
        include extensions of lz, U3, and (normed) number of Guttman
        errors.
