I am doing a multinomial logistic regression on outcome variable d. This variable has three levels: 0, 1 and 2. In the code below, is the effect of predictor a in d-levels 1 and 2 each compared to effect of a in d-level 0?
proc logistic data=test;
class d (ref='0') / param= ref;
model d = a / link=glogit clodds=pl;
run;
Thank you!
