Traditional methods for evaluating contingency table models based on chi square statistics or quantities derived from them are not attractive in many applied research settings. The two-point mixture index of fit, * , introduced by Rudas, Clogg and Lindsay (RCL: 1994) provides a new way to represent goodness-of-fit for contingency tables. This study: (a)(More)
Current approaches for studying differential item functioning (DIF) using manifest groups are problematic since these groups are treated as homogeneous in nature. Additionally, manifest variables such as sex and ethnicity are proxies for more fundamental differences – educational advantage/disadvantage attributes. A simulation study was conducted to(More)
