st: dot for standard error in xtlogit

[Garry Anderson <g.anderson@unimelb.edu.au>]

Hi,

I am receiving a dot for the standard error that relates to a coefficient 
in xtlogit
Panels with zero positives do not seem to be the problem as other 
estimations with xtlogit that do have some panels with zero positives do 
not have a dot in the results.

Kind regards, Garry
