WPerfit: A Program for Computing Parametric Person-Fit Statistics and Plotting Person Response Curves.
Ferrando, Pere J.; Lorenzo, Urbano
Educational and Psychological Measurement, v60 n3 p479-87 Jun 2000
Describes a program for computing different person-fit measures under different parametric item response models for binary items. The indexes can be computed for the Rasch model and the two- and three-parameter logistic models. The program can plot person response curves to allow the researchers to investigate the nonfitting response behavior of inconsistent examinees. (SLD)
