Multinomial repeated logistic regression
Posted: Fri Jul 31, 2015 8:20 pm
I have a longitudinal data set that is comprised of a set of physician prescription patterns (three unordered categories). Within each physician there are two assessments, pre- and post-test. At the pre- and post-test, there are 3-140 responses for each physician. So I have these measurements nested in times, and times nested in physicians. There are several educational groups that form an IV. It's not really the type of data I was expecting (normally one gets one measurement at each time period), but it's what I was given and I'm wondering if there's a way to use all of the data. Can this be set up as a 3-level longitudinal model in MLwiN? I realize that with only two time periods I can't do any growth curves, but I'm normally a SAS user, and it does not provide for repeated measures designs in the multinomial case. What do you think?
