proc glimmix data=mydata;
class myclass mygroup myid;
model count_response = mycovariate myclass / dist=poisson link=log offset=log_time;
random intercept / subject=myid;
random intercept /
run;

We would like to view the estimates in the original scale by exponentiating them. One way is the following:

data exp_estimates;
set estimates;
exp_estimate = exp(parameter_estimate);
run;

But I was wondering if an statement can be added directly in proc glimmix.

Estimates of what?

The model coefficients are based upon the appropriate model form for a Poisson model. I don't know what it means to ask for these on "the original scale".

estimates are in log form from the poisson. For interpretation purposes, it is easier to interpret the estimates as counts and not log counts.

Do you mean "predicted values"?
