I am just getting started with Mplus. Coincidentally, I'm investigating the behaviour of so-called probabilistic latent semantic analysis (Hoffman 1999) , which is a fancy name for a latent mixture model with nominal observed and unobserved vars. Parameters are estimated using EM. I have implemented the procedure in software, but I am wondering if Mplus is capable of fitting these models as well -- and if so, whether there are scalability issues with using Mplus that make in impractical for this application.

A model with nominal observed and categorical variables using EM is possible in Mplus. See Example 7.7 in the user's guide.
