This package\nallows users to implement extensions of the Mantel-Haenszel DIF\ndetection procedures in the presence of multilevel data based\non the work of Begg (1999)\n<doi:10.1111/j.0006-341X.1999.00302.x>, Begg & Paykin (2001)\n<doi:10.1080/00949650108812115>, and French & Finch (2013)\n<doi:10.1177/0013164412472341>.",
