difR: Collection of methods to detect dichotomous differential item
functioning (DIF) in psychometrics
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
than one focal group.
