[Limdep Nlogit List] BoxCox

[Ana I Sanjuan]

Dear LIMDEP users,

I´m trying to run a Box-Cox regression with possible different 
transformations on the dependent and one independent variable, using the 
MLE option  (I tried also with grid search) and Model = 4. I initialize 
Lambda and Theta, either at 0 or 1, but I get the following error:

Error   395: BOXCOX:;LAMBDA=value not found or MODEL=3 & no THETA found.

What am I doing wrong?

Thank you for any help
