The SAS macro-program %AnaQol to estimate the parameters of item responses theory models. %Anaqol requires the %Gammasym and the %Rasch SAS macro-programs. This macro-program allows: computing the Cronbach alpha and realizing the Step-by-step Cronbach alpha procedure; drawing classical and cumulative traces of dichotomous and polytomous items; ;drawing logistic traces of dichotomous items; estimating the parameters of the Rasch model, Birnbaum model, OPLM, Partial Credit model and Rating Scale model; drawing empirical and theorical traces or ICC of the items; realizing fit tests under the dichotomous models; drawing information curve and map Items/scores under the Rasch models; Computing INFIT and OUTFIT indexes per items or per individual with dichotomous models.
