Are any syntactical changes needed for the commands I use in SAS when doing an exploratory factor analysis with dichotomous data? My data set has a sample size of 277 with 32 variables, 7 of which are true/false and 25 of which are multiple choice, but all of which have a right answer. Thank you!
This looks like IRT. Do you have access to SAS/STAT13.2? If so, you might look at PROC IRT for a start.
