A Monte Carlo Comparison of Parametric and Nonparametric Polytomous DIF Detection Methods.
Bolt, Daniel M.
Applied Measurement in Education, v15 n2 p113-41 2002
Compared two parametric procedures for detecting differential item functioning (DIF) using the graded response model (GRM), the GRM-likelihood ratio test and the GRM-differential functioning of items and tests, with a nonparametric DIF detection procedure, Poly-SIBTEST. Monte Carlo simulation results show that Poly-SIBTEST showed the least amount of power across all conditions. Discusses implications for DIF detection. (SLD)
