should I use regression vs SEM

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.
