%description
Provides a collection of standard methods to detect differential item
functioning among dichotomously scored items. Methods for uniform and
non-uniform DIF, based on test-score or IRT methods, for comparing two or
more than two groups of respondents, are available (Magis, Beland,
Tuerlinckx and De Boeck,A General Framework and an R Package for the
Detection of Dichotomous Differential Item Functioning, Behavior Research
Methods, 42, 2010, 847-862 <doi:10.3758/BRM.42.3.847>).
