[Limdep Nlogit List] WTp estimation

[William Greene]

Medard.  WTP for all variants of the RP logit model is described in
Chapter N29.  That would be good for the S-MNL and GMXL.  I'm
not sure what the G-MNL model is.  WTP is generally a ratio of
coefficients, though in RP models, the WTP is computed for each
individual.  P values for LR statistics are generally not computed.
I'm not sure what the P-value at 5% is.  You can use CALC to look
up critical values for chi-squared if you wish.  The function
CTB(prob,df) returns the critical value for probability prob with
degrees of freedom df.
