obtaining adjusted rate for one group

SWEETSAS — Wed, 28 Jan 2015 18:14:56 GMT

Hello:

Please, I want to obtain adjusted event rate using genmod procedure. For two groups this is quite easy using the lsmeans statement. My outcome is a count of event which follows Poisson distribution.

That is,

proc genmod data=me;

class group;

model outcome=group age weight/link=log dist=poisson

lsmeean group/exp;

run;

Where group variable has two groups code 1 if group=0 and 0 if group=1;

Now, I have only one arm, but I will still like to obtain the adjusted rate (i.e. adjusting for age and weight). Does any one know if this is possible in the genmod procedure? I will also like to know if similar adjusted estimate is possible using the GLM procedure as I have another variable that is continuous.

Thanks,

Jack.

The intercept is the source for the adjusted rate in a single arrm trial. You "adjust out" for the continuous covariates, and get the "rate" at the mean values of the covariates.
