Subject:      Analysis Of Parameter of interaction terms in Proc Genmod (GLM)
Comments: To: sas-l@uga.edu

Below is part of Analysis Of Parameter from my Proc Genmod procedure.
I am trying to model insurance premium against interaction of Group
(grp), longevity (long) and Number of Claims (NumC). However, I find
the results repeated twice (N, Y) for some combination of Grp, Long
and NumC. The classification of variables are exclusive and
exhaustive. What does the result mean? How to get rid of the
repetitions.

Your advice is greatly appreciated.
