Abstract: pcmtest evaluates the fit of the data to a Partial Credit model or a Rating Scale model previously estimated with pcmodel (R1m and Si First order tests). Several graphical representations can be easily obtained: distribution of the latent trait depending on the individual scores, graphic of MAP, graphic of the groups contribution to the R1m statistic, and graphic of the observed and expected score distribution.
