But ESTIMATE may be questionable; what about as the following code?
[code:1o4wy5fu]estimate 'xcc 0 vs. 1' xcc -1/exp;[/code:1o4wy5fu]
The reason is, you are using reference coding in CLASS statement but GLM coding ESTIMATE;
the identical code is
[code:1o4wy5fu]proc genmod data=a;
class xcc;
---;
estimate 'xcc 0 vs. 1' xcc 1 -1/exp;
run;[/code:1o4wy5fu]
By the way, you need to look at L'Beta estimate and its CI in ESTIMATE/CONTRAST part.
