[Limdep Nlogit List] LCRPLOGIT question

[Kolady, Deepthi Elizabeth P]

Dear Professor Greene,

Thank you very much for the quick response and the clarification on LCRPLOGIT and RH2 command. In addition to demography, I want to include climate change perceptions as another choice invariant variable.

 I I want to estimate class-wise WTP estimates for various carbon market attributes in one step. If I understand your response and the manual correctly, LCRPLOGIT allows me to do that. Am I right? Sorry for not communicating it clearly earlier.

Thanks again for your timely help.

Best regards,
Deepthi

Deepthi. LCRPLOGIT is for latent classes and random parameters. Your description sounds like you only want LCLOGIT - latent classes.  Note that you can't separate observations into classes, by construction the classes are latent.  You can, post estimation, make your best guess as to who is in which class - please see the NLOGIT manual for details.  RH2 is not the latent class determinants.
RH2 is for choice invariant variables such as Age or Income.  To make the class probabilities conditional, you will use ;LCM = list ... where the variables should be choice invariant as well.
