Dear statalisters,
as I only have little experience, I would be happy if you could try to answer my question.
After entering industry dummies into probit or multinomial logit models (or other models, I haven't tried...), I sometimes experience the problem that standard errors of the coefficients of the dummies tend to infinity and p-values tend to one. I am working with firm level surveys.
Do you have an explanation for this phenomenon?
Thank you for your consideration.
Florian
