I have some related questions, hopefully you can help me out:
a) I am trying to find out when to use chi square difference testing and when log likelihood difference testing (using the Satorra-Bentler Scaled Chi-Square). Are these interchangeable options? If not, when should I use one or the other?
b) In my case, I am testing a multilevel mediation model and I am adding predictors step-by-step. In the first steps the model is saturated, so the chi square is zero. Can I use the log likelihood difference test here?
