A set of functions to perform Raju, van der Linden and Fleer's (1995) Differential Item and Item Functioning (DFIT) analyses. It includes functions to use the Monte Carlo Item Parameter Replication (IPR) approach (Oshima, Raju, & Nanda, 2006) for obtaining the associated statistical significance tests cut-off points.
