Two-Stage Equating in Differential Item Functioning Detection under the Graded Response Model with the Raju Area Measures and the Lord Statistic.
Hidalgo-Montesinos, Maria Dolores; Lopez-Pina, Jose Antonio
Educational and Psychological Measurement, v62 n1 p32-44 Feb 2002
Examined the effect of test purification in detecting differential item functioning (DIF) by means of polytomous extensions of the Raju area measures (N. Raju, 1990) and the Lord statistic (F. Lord, 1980). Simulation results suggest the necessity of using a two-stage equating purification process with the Raju exact measures and the Lord statistic to increase DIF detection. (SLD)
