Estimating the Importance of Differential Item Functioning.
Rudas, Tamas; Zwick, Rebecca
Journal of Educational and Behavioral Statistics, v22 n1 p31-45 Spr 1997
The mixture index of fit (T. Rudas et al, 1994) is used to estimate the fraction of a population for which differential item functioning (DIF) occurs, and this approach is compared to the Mantel Haenszel test of DIF. The proposed noniterative procedure provides information about data portions contributing to DIF. (SLD)
