Robustness redressed : an exploratory study on the relationships among overall assumption violation, model-data-fit, and invariance properties for item response theory models

This study compares item and examinee properties, studies the robustness of IRT models, and examines the difference in robustness when using model-data-fit as a robustness criterion. A conceptualization of robustness as a statistical relationship between model assumption violation and invariance pro...
