Latent variables Manifest variables Continuous Categorical Continuous Factor analysis Latent profile analysis Categorical Latent trait analysis Latent class analysis

based on latent class (LC) analysis that is especially suited for dealing with categorical indicators, such as dichotomous, ordinal, and nominal variables, and counts. The approach is called latent class factor analysis (LCFA) because it combines elements from LC and traditional FA. This LCFA model is one of the LC models implemented in the Latent GOLD program (Vermunt & Magidson, 2000, 2003).
