WebLatent class analysis is used to classify individuals into homogeneous subgroups. Individual differences in observed item response patterns are explained by differences in latent class membership (Geiser, 2013). For the case with only dichotomous variables X = { 0, 1 }, the latent class analysis (LCA) model for a single item can be written as: Webgiven latent class y. In particular, we note that within a specific class, (local) independence applies: the estimated joint prob-ability of observing some N-element categorical pro-file is the product of the respective marginal proba-bilities. The job of latent class analysis is to find the size of each latent class and the estimated ...
