Prediction & causation

Regression can be used for both prediction and causation. While not a form of validity, it may be worth exploring whether there is a causal relationship between various dimensions of the survey. brand_rep_sem is a loaded lavaan model which regresses our second factor F2 on the other two factors F1 and F3 of our brand reputation survey. Let's check for a causal relationship between the factors.
