Advantages of SEM over Regression
- Structural Equation Modeling (SEM) is a second generation multivariate method that was used to assess the reliability and validity of the model measures.
- confirmatory factor analysis (CFA) was selected instead of multiple regression.
- Multiple Regression is a special case of Structural Equation Models (SEM).
- If your variables are all directly measured variables, then use multiple regression. If you have latent variables (ie. factors defined by indicators), you should use SEM.
