Re: [R] mixture models/latent class regression comparison

Dear Carson, I have never used mmlcr for this, but quite generally when fitting such models, the likelihood has often very many local optima. This means that the result of the EM (or a similar) algorithm depends on the initialisation, which in flexmix (and perhaps also in mmlcr) is done in a

[R] mixture models/latent class regression comparison

Dear list, I have been comparing the outputs of two packages for latent class regression, namely 'flexmix', and 'mmlcr'. What I have noticed is that the flexmix package appears to come up with a much better fit than the mmlcr package (based on logLik, AIC, BIC, and visual inspection). Has anyone e

Re: [R] mixture models

Dear Rita, The depmixS4 package handles such models. It is still in beta testing so I would appreciate it if you share your experiences with it. Also let me know if you have further questions. Best, Ingmar On 16 Mar 2009, at 10:19, Rita Gaio wrote: Dear R users, I want to apply latent

[R] mixture models

Dear R users, I want to apply latent class models (mixture models) with covariates in the case of continuous and categorical variables. My questions are the follow: a) the only package in R that can handle mixture models with data of mixed type is moc (which unfortunately was left orphaned recent
