abstract: 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.
