st: option -robust- for -glm- and -poisson-
I'm running a loglinear model (categorical data; Stata V.9, Windows XP)
using the -glm- (option: fam(pois)) and the -poisson- command.
I have a question about the option -robust-: When is it reasonable to
use this option? I have read that it makes the confidence intervall
narrower. Are there other reasons for / benefits of using this option?
Any comments would be appreciated!
