M. Dutta? Did you request them?  They are saved as matrices, not
listed with the output, when you do.

Subject: [Limdep Nlogit List] Fwd: Problem in WTP calculation

Hi,

I was using NLOGIT  for modeling utility equations. However, after
getting a model I cannot find the WTP for aparticular attribute for the
same. Can anyone please suggest me the suitable commands for the same.

The following is one of my utility model output:
