Subject: Re: [Limdep Nlogit List] Exploded and negative wtp estimates

Greetings to you all!
I estimated wtp using three models: RPL, Generalised mixed logit in
preference space and in wtp space. My estimates are extremely big - I have
tried the normal, triangular and log normal distributions. They become
bigger if I use more than 100 random draws, halton draws don't make them
any better. Secondly, they are negative yet the MNL estimates are positive
and my price parameter is negative. What could be the reason/problem for
negative and explosive wtp estimates?


Best regards,

Medard
