Detection of Differential Item Functioning Using Lagrange Multiplier Tests. Research Report 96-02 [electronic resource] / Cees A. W. Glas.

In this paper it is shown that differential item functioning can be evaluated using the Lagrange multiplier test or C. R. Rao's efficient score test. The test is presented in the framework of a number of item response theory (IRT) models such as the Rasch model, the one-parameter logistic model...
