Isi artikel

A program is described for computing different person - fit meaures under different parametric item response models for binary items. The indices computed are the standardized log - likelihood index Iz, is the standardized extended caution index ECI4z, and the chi - square statistic of trabin and weiss. These indices can be computed for the rasch model and the two - and three - parameter logistic models. The program can plot person repsonse curves, which allow the researcher to investigate the kind of non fitting response behaviour that is present in examinees who are detected as inconsistent.
