I have a dataset with approximately 1900 observations made up of patients (probands) and family members (brother, sister, mother, father). There are approximately 600 families, each with 2-4 members. I want to perform a latent profile analysis with 5 continuous measures. How do I model the clustering between families?
Clustering for LPA can be handled in two ways in Mplus - TYPE=COMPLEX MITXURE; or TYPE = TWOLEVEL MIXTURE; These two approaches are described in the introduction to Chapter 9 in the Mplus User's Guide. This introduction is also available at the Mplus website.

I would like to run a model similar to 7.12 LCA with covariates. Except I want it to be a profile model with a categorical covariate. I have tried to run the model with the covariate X denoted as categorical and %overall% C#1 on x; but it doesn't run. It will run if I do not denote X as categorical. THis is the error message: *** ERROR The following MODEL statements are ignored: * Statements in the OVERALL class: C#1 ON X *** ERROR One or more MODEL statements were ignored. These statements may be incorrect or are only supported by ALGORITHM=INTEGRATION.
