An investigation of the likelihood ratio test for detection of differential item functioning

Cohen, Allan S.; Kim, Seock-Ho; Wollack, James A. - 1996

Type I error rates for the likelihood ratio test for detectingdifferential item functioning (DIF) were investigatedusing monte carlo simulations. Two- andthree-parameter item response theory (IRT) modelswere used to generate 100 datasets of a 50-item test forsamples of 250 and 1,000 simulated...
