[Limdep Nlogit List] Kernel Densit Estimator/Log likelihood ratio test

[Santa Dutta]

Sir,

I have the following doubts while working with NLOGIT(3.0):

1)Can the kernel density estimator be used as a guide to identify the type
of distribution suitable for a particular parameter while estimating Random
Parameter logit Models?

2)Log likelihood cannot be used as a basis for comparing two models with
same number of parameter estimates(degrees of freedom).
Can you please suggest some test which can be used for model
selection/identification in this case.

Can NLOGIT 4.0 help me in any way regarding these?

Regards,

S.S.Dutta
