%description
Methods to detect differential item functioning (DIF) in dichotomous and
polytomous items, using both classical and modern approaches. These
include Mantel-Haenszel procedures, logistic regression (including ordinal
models), and regularization-based methods such as LASSO. Uniform and
non-uniform DIF effects can be detected, and some methods support multiple
focal groups. The package also provides tools for anchor purification,
rest score matching, effect size estimation, and DIF simulation. See
Magis, Beland, Tuerlinckx, and De Boeck (2010, Behavior Research Methods,
42, 847–862, <doi:10.3758/BRM.42.3.847>) for a general overview.
