[Limdep Nlogit List] Error 636

[Kalyan Chakraborty]

Prof. Green, Thank you so much. I read a few papers that had a similar
number of observations as I have, and used the same model. As a result, I
thought I might be able to run it. But I am not aware of the program they
used. I was able to run with a different set of data for 57 countries for 9
years of data, on limdep no problem. Do you recommend reducing the number
of variables? The values are mostly one or two digits after I took the log
transformation.

Thank you again,
Kal
