Generalized Mantel–Haenszel Estimators for Simultaneous Differential Item Functioning Tests

Educational and Psychological Measurement, 2022
The Mantel–Haenszel estimator is one of the most popular techniques for measuring differential item functioning (DIF). A generalization of this estimator is applied to the context of DIF to compare items by taking the covariance of odds ratio estimators between dependent items into account.
