Re: [R] Vermunt's LEM in R

Basically I do LCA, followed by some kind of analysis intended to validate the solutions. For example, I would create latent class solutions for each gender based on four dichotomic indicators of psychosis. Next, I would look at the interaction of current psychiatric status (the classes) and past psychiatric diagnosis to predict institutional treatment use (logit or logistic models). poLCA is a little limited for this purpose; I would have to use it in combination with some other package. For example, it doesn't provide residuals for the indicators, or the Cressie-Read statistic.

poLCA is an option, as is randomLCA, flexmix, and depmixS4, and there are likely to be more What specific models are you interested in? Best, Ingmar

I guess LEM is a software for latent class analysis. If so, you may

want to have a look at poLCA package.
