Package: DIFplus Title: Multilevel Mantel-Haenszel Statistics for Differential Item Functioning Detection Version: 1.1 Authors@R: c(person("Shenghai", "Dai", role = c("aut", "cre"), email = "s.dai@wsu.edu"), person("Brian F.", "French", role = "aut"), person("W. Holmes", "Finch", role = "aut"), person("Andrew", "Iverson", role = "aut")) Author: Shenghai Dai [aut, cre], Brian F. French [aut], W. Holmes Finch [aut], Andrew Iverson [aut] Maintainer: Shenghai Dai 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) , Begg & Paykin (2001) , and French & Finch (2013) .
