Description: Clustered or multilevel data structures are common in the
        assessment of differential item functioning (DIF), particularly
        in the context of large-scale assessment programs. This package
        allows users to implement extensions of the Mantel-Haenszel DIF
        detection procedures in the presence of multilevel data based
        on the work of Begg (1999)
