Sorry, me again!
I've just obtained this error
*** FATAL ERROR MODELS WITH LATENT CLASS VARIABLE REGRESSION CAN NOT BE ESTIMATED WITH THE BAYES ESTIMATOR.
Is this due to the problem of obtaining an appropriate conjugate prior for the multinomial parameters?
Assuming I am right, given that MH is not currently available for mixtures, do you have a recommendation? I'm mindful of the fact that I must make additional assumptions if I wish to render my covariate dependent for the imputation step.
Since on this occasion my X is binary, I'm wondering about a knownclass solution . . .
Tihomir reminded me that if you have a 2 x 2 latent class variable situation you can always turn it into a single latent class variable with 4 classes. But then you have to add various parameter constraints to get the same model and that may not be straightforward.
