Is it possible in SPlus to create simulated data based on a defined covariance table? I want to create a simulated data set for dichotomously scored items and have the items inter-correlated. For example, Item 1 2 3 4 5 1 - .44 .37 .67 .51 2 - .49 .39 .62 3 - .74 .53 4 - .47 5 - The raw data I want to simulate would consist of 1s and 0s for each item to represent correct and incorrect scores. It would be further helpful to be able to specfiy average score by examinee, average score by item, and a point biserial for each item. Anyone know if such magic can be pulled off in SPlus?
