Sammanfattning	Latent transition analysis (LTA) is a longitudinal extension of latent class analysis that models how individuals move between qualitatively distinct, unobserved categories over time. In education it represents students as belonging to learner profiles or developmental stages — for example, types of motivation, reading-strategy profiles, or mastery stages — and estimates the probabilities of transitioning from one profile to another between time points. It answers not only how many kinds of learners there are, but how learners change type as instruction and development unfold.	Latent class analysis identifies unobserved subgroups — latent classes — within a population by finding patterns of responses across a set of categorical observed indicators. It is the categorical-variable counterpart of cluster analysis, but grounded in an explicit probabilistic model, and is widely used in social, health, and behavioral sciences to discover typologies in survey or diagnostic data.
