As Martin also signalled, it's in e(V), not e(b).

Dear Stata,
I have done logistic regression with logit.
How can I look at the variance-covariance matrix? I understand it is saved
in something called e(b), but I can´t see it!
Can I use one of the coefficients like it is possible to use betas in some
calculations? How to do it!
