Title: Some traditional methods to detect dichotomous differential item
Author: Sebastien Beland (UQAM), David Magis (KU Leuven) and Gilles
Description: The difR package contains several traditional methods to
detect DIF in dichotomously scored items. Both uniform and
non-uniform DIF effects can be detected, with methods relying
upon item response models or not. Some methods deal with more
