R help - Dec 2011 - Latent class multinomial (or conditional) logit using R?

Hi everyone?

Does anybody know how can I estimate a
Latent class multinomial (or conditional) logit using R?

I have tried flexmix, poLCA, and
they do not seem to support this model.
thanks in advance

You may have a look at lcmixed/flexmixedruns in package fpc. This provides 
flexmix methods that can be used to fit latent class models with locally 
independent multinomials (no logits, though, and I'm not sure that for 
categorical data only this is much different from what poLCA offers).

Best regards,
Christian

Hi Christian,
Thanks a lot for the suggestion.
As you expected, lcmixed does not provide more functionality than poLCA for
the case of
only categorical data...
Do you know whether there is an explanation (some technical difficulty I 
may be missing, I am Economist so it is very likely) of why I can fit a
Poisson, a logit latent class
model but not a conditional logit?

In fact, I started using R when I realize that my (very rudimentary) EM
script written in Matlab
had tons of problems to converge.
Now I start wondering if there is some specific situation I should be aware
of.

Thanks a lot again
