now i have a question about the item weighting issue. If the polychotomousy socred items are set by ISGROUP=. Say, they are have different score value from the dichotomously scored items. is it necessary to set the IWEIGHT value according to their raw scores?
For instance, if the possible response scores for one item are 0,1,2,3,4,5, then the weighting of that item is 5,yes?
