• lordif: An R Package for Detecting Differential Item Functioning Using Iterative Hybrid Ordinal Logistic Regression/Item Response Theory and Monte Carlo Simulations (2011, methodology): “The S−X2 model fit statistics (Kang and Chen 2008; Orlando and Thissen 2003) were examined for the graded response model (Samejima 1969) using the IRTFIT (Bjorner et al. 2006) macro program.”
• Performance of the generalized S-X2 item fit index for the graded response model (2011, methodology): “Recently, Kang and Chen (2008) successfully generalized the use of S-X2 to polytomous IRT models such as the generalized partial credit model (GPCM; Muraki 1992), the partial credit model (PCM; Masters 1982), and the rating scale model (RSM; Andrich 1978).”
