What Is Latent Class Analysis? - The Analysis Factor

www.theanalysisfactor.com

Live Enter Latent Class Analysis (LCA). LCA is a measurement model in which individuals can be classified into mutually exclusive and exhaustive types, or latent classes, based on their pattern of answers on a set of categorical indicator variables. (Factor Analysis is also a measurement model, but with continuous indicator variables).

FAQS

Do online classes have tests?

Not all online classes have proctored exams. But if they do, online students may need to visit a local testing site, with an on-site proctor.
