WebIntroduction. Structural equation modeling is a linear model framework that models both simultaneous regression equations with latent variables. Models such as linear regression, multivariate regression, path analysis, confirmatory factor analysis, and structural regression can be thought of as special cases of SEM. Webthe DynamicFactor model handles setting up the state space representation and, in the DynamicFactor.update method, it fills in the fitted parameter values into the appropriate locations. The extended specification is the same as in the previous example, except that we also want to allow employment to depend on lagged values of the factor.
