Hi Richard,
Thanks for your reply. I read the threads you told me, but in this
example is only for one regresion, so there is only one coefficients
covariance matrix e(V)... I have two: one for year=1 and another for
year=2. Also, here uses the option -tracelvl- with the -mfx- command
to get the second derivates, but for -gologit2- the -mfx- command not
works and the -mfx2- command doesn't have this option (I don't know if
the -marfeff- command does, but I tried to use this after -gologit2-
and it doesn't work too)... What can I do?
Thanks in advance
Bests
