Dear Stata experts,
I have grouped data and want to estimate incidence rate each year. How can I set 'stset' when I don't have individual level data. Do I need to expand data with certain assumptions?
region year agegp cases population
1 1994 0-4 2 5000
1 1994 5-9 5 2548
1 1994 10-14 6 2547
1 1994 15-19 15 7521
1 1994 20-24 75 7896
I am using stata 10.
Sorry for brevity of message but cannot think what else information should I provide.
Thanks for your help.
