WebApr 11, 2024 · Abstract. Researchers face a tradeoff when applying latent variable models to time-series, cross-sectional data. Static models minimize bias but assume data are … WebA latent variable model is a statistical model that relates a set of observable variables (also called manifest variables or indicators) to a set of latent variables.. It is assumed that the responses on the indicators or manifest variables are the result of an individual's position on the latent variable(s), and that the manifest variables have nothing in …
