I am running a VPC stratified on CMT with N=14. When I looked at my file
VPC_results I found the following for my CMT=11 and CMT=23. This resulted
in a confidence interval for the 95 percentile at this time to be much
higher than calculated independently with SAS. Is there a reason that this
occurred and can it be corrected to give the proper N=14?
