These commands initiate the scoring of individual respondents and are optional. MET=2 refers to expected a posteriori (EAP, Bayes) estimation. Other options are available and explained in the BILOG manual. IDIST=0 indicates that no prior distribution of scale scores are provided (standard normal assumed). RSC=0 indicates that no rescaling of respondents is necessary. NOPRINT tells BILOG not to display the scores.
