[Limdep Nlogit List] problema latent class model

[William Greene]

Dear Elias Jose' Gordillo Cha'vez:
The student version of nlogit6 allows 1500 individuals with 4 choices, or
6,000 lines of data.
It should be able to handle your data set.  You can read in all 6,000 lines
of data (2,628 in
your case).  For the nlogit program, you have only 876 individuals and 3
choices.  When you
are fitting the model, if you are specifying a choice experiment, you will
have 146 individuals
and ;PDS=6.
I'm sorry I can't advise about the model. If nothing is "significant," the
model may be
misspecified or inappropriate for the data.
Sincerely,
B. Greene
