Logistic Discriminant Function Analysis for DIF Identification of Polytomously Scored Items.
Miller, Timothy R.; Spray, Judith A.
Journal of Educational Measurement, v30 n2 p107-22 Sum 1993
Presents logistic discriminant analysis as a means of detecting differential item functioning (DIF) in items that are polytomously scored. Provides examples of DIF detection using a 27-item mathematics test with 1,977 examinees. The proposed method is simpler and more practical than polytomous extensions of the logistic regression DIF procedure. (SLD)
