WebJan 23, 2015 · One reason: measurement models help to evaluate how reasonable your theory of construct measurement is. If you skip right to a structural model and get bad model fit, it could be because your theory of construct measurement sucks, or because your theory of structural construct relations sucks. WebApr 13, 2024 · 3. Structural equation models allow for estimation of complex networks including latent and observed variables, and endogenous and exogenous factors. When an SEM is fit, the model results are summarized in terms of a number of fit indices. I assume these indices (and their p -values) are variations of goodness-of-fit-tests.
