Rodrigo,

Which command are you using for the nested logit: gllamm, nlogit, or
nlogitrum? Exactly which syntax did you use? Can you estimate simpler
nested logit models, e.g., the models in [R] nlogit? If you -set trace
on- do you see any output?

I am trying to estimate a nested logit model with the following
characteristics:

-       Location choice firm in 25 countries (upper level) and 246
regions belonging to those countries (lower level)
-       I have 6,475 location choices.
-       Explanatory variables are economic country and region
characteristics.

The estimation does not work. It recognizes the nested structure but
after that the computer seem to run the model but not results appear,
even no iterations.

I was wondering whether there is a maximum size restriction in the
number of alternatives, nests or observations to estimate a nested logit
with Stata.
