Hi, I have a dataset with ~170 binary dummy variables (clinical indicators) and close to 1,000,000 rows of data. I'm interested in modeling the 170 dummy variables as well as the second order interactions between them. I believe there should be n*(n-1) / 2 = 14,365 2nd order interactions, which makes the dataset very wide (as well as long). I've tried writing a model call to HPGENSELECT into a text file with all variables, but even with a small subset of observations (1000), the code ran for a very long time before I finally killed it. Do you have any suggestions for getting something like this to run? A valid answer is "that's a bad idea, why would you do that" 🙂 SAS Version: 9.04M5 Thanks in advance!
