Which is the best choice to be made for :
- the link function
- the distribution
Hi Jan,
PROC GENMOD only offers cumulative logits as possible links, which may not
be appropriate due to the proportional odds assumption. You should also
look into glogits with PROC LOGISTIC -- it computes a score test for the
POA; GENMOD does not.
