Detecting Violations of Unidimensionality by Order-Restricted Inference Methods

Detecting Violations of Unidimensionality by Order-Restricted Inference Methods

The assumption of unidimensionality and quantitative measurement represents one of the key concepts underlying most of the commonly applied of item response models. The assumption of unidimensionality is frequently tested although most commonly applied methods have been shown having low power agains...
