Dear stata users;

I am trying to run nbreg as below;

nbreg y x1 x2 if x3==1

where x3 is a dummy variable and I want to do the regression only
using the observations where x3 is equal to 1. However I receive an
error message saying that "if is not allowed". Could you suggest a way
to do this?

Thank you very much,
Sarah
