In this case, I have information on person year and standard mortality rate for each stratum. As I checked the materials online, no one used two offsets at the same time. So I'm wondering can I do this? (the following is the SAS code)

proc genmod data=bomb3;

model casenum = age followuptime dose

/ dist=poisson offset=logcancerexp offset=logpys;

run;
