Woul you please shed light on the fit indices for CFA and SEM.
The fit indices are similar in the CFA and SEM that I run. I came across a paper that mentioned "the better fit indices of SEM indicates the structural model better explains the data". This sounds rational, but makes me worried whether my structural model is no better compared to when all variables are freely related. The structural model is a mediating model, and I've tested the mediation via bootstrapping.
