My question is that when we do CFA of SEM in AMOS by using 2nd order latent modeling. where error terms are required to be attached? either just with initial items (Factors) or also with 1st order latent variable that is acting as factors for 2nd order construct?
When you do second order CFA, the arrow from the second order construct are pointing to the first order construct. Thus, the first order construct has become the dependent construct since the arrow pointing to it from its second order constrcut. Thus, at the first order construct you need to put one residual.
Hi Amir, to keep things simple in my mind I always try to remember that if a variable (latent or observed) has an arrow pointing at it, then it must have an error term.
Cheers, mark
