I can't ... I don't know why but I can't When I use it:
logit <- glm(bach ~ egp4 + programa, weight=wst7, family=quasibinomial(link"logit")) I reach the same betas that in STATA, but the hypothesis test, the t value, and the std. error is different. I think that the solution can't be so far from this...
