Description: Root Expected Proportion Squared Difference (REPSD) is a
        nonparametric differential item functioning (DIF) method that
        (a) allows practitioners to explore for DIF related to small,
        fine-grained focal groups of examinees, and (b) compares the
        focal group directly to the composite group that will be used
        to develop the reported test score scale. Using your provided
        response matrix with a column that identifies focal group
        membership, this package provides the REPSD values, a simulated
        null distribution of possible REPSD values, and the simulated
        p-values identifying items possibly displaying DIF without
        requiring enormous sample sizes.
