Moderation analysis is typically conducted by incorporating a single variable (e.g., gender, baseline severity) as a moderator into a multiple regression model. By using LCA, researchers can identify subgroups of people exposed to a common set of factors, and who, therefore, may respond differently to intervention. That is, latent class membership can be used as the moderating variable in multiple regression.
