A key question is if the latent class variable is a within- or a between-level variable. If the classes represent subjects, the latent class variable should be on the Between = list in a Type=Twolevel analysis. The User's Guide shows several such examples.
Thank you Dr. Muthen. I've attempted the Type=Twolevel analysis, but am unable to identify the latent classes in the output. If it helps, I am only looking at LCA to determine classes and class membership in the measurement model at this point.
