Abstract :
[en] Differential item functioning (DIF) is an important issue of interest in psychometrics and educational measurement. Several methods have been proposed in the last decades to identify items that function differently between two (or more) groups of examinees. Starting from a framework for classifying DIF detection methods and from a comparative overview of the most traditional methods, an R package for nine methods, called difR, is presented. The commands and options are briefly described, and the package is illustrated through the analysis of a data set on verbal aggression.
