Our latest video provides a 15-minute conceptual overview of latent transition analysis (LTA). Methodology Center Investigator Bethany Bray uses an analysis about ex-smokers to demonstrate the types of questions LTA can answer and how LTA differs from LCA.
Latent transition analysis (LTA) and latent class analysis (LCA) are closely related methods. LCA identifies unobservable (latent) subgroups within a population based on individuals’ responses to multiple observed variables. LTA is an extension of LCA that uses longitudinal data to identify movement between the subgroups over time.
