An explanatory differential item functioning (DIF) model by the WinBUG 1.4
This study proposed a multilevel logistic regression model to evaluate a source of DIF. The model accounts for the three levels nested structure of the data and combines results of logistic regression analysesto identify level-3 unit characteristic variables that explain a DIF variation. A simulatio...

| Summary: | This study proposed a multilevel logistic regression model to evaluate a source of DIF. The model accounts for the three levels nested structure of the data and combines results of logistic regression analysesto identify level-3 unit characteristic variables that explain a DIF variation. A simulation study is presented to assess the adequacy of the proposed models. The parameters of the proposed models were estimated by usinga Bayesian approach implemented by the WinBUGS 1.4. |
