Dear Stata users,
Is there a way to fit a Poisson regression to
stratified data?
For example I have the following dataset:
. cl x i1 i2 stratum
x i1 i2 stratum
1. 27 0 1 1
2. 18 0 1 2
3. 12 1 0 2
4. 15 0 1 2
5. 14 1 0 2
6. 9 1 0 3
7. 8 1 0 3
8. 13 0 0 4
9. 11 0 1 4
10. 26 1 0 4
11. 3 1 0 5
12. 5 1 0 5
13. 10 0 0 5
14. 7 0 0 5
15. 1 0 0 6
Where �x- is a count, d1 and d2 are dummies, and
stratum is a stratification variable.
I would like to fit
. poisson x d1 d2 <-- stratified by �stratum-
Any suggestions?
Thank you in advance,
Ricardo
