Dear Dr. Muthen,
I'm trying to conduct multilevel path analysis using Mplus. In the model, I want to test a cross-level interaction using random slope: ------------ %WITHIN% s1| Y ON X_within; !the random slope between the DV and IV
%Between% Y WITH X_within; Y ON X_moderator; s1 on X_moderator; ! The 2-way interaction
X_within with X_moderator; ------------ Question 1: I understand we should covary all exogenous variables (in this case, X_within and X_moderator). Should I also covary s1 and the dependent variable Y? Question 2: Is s1 treated as a endogenous variable? Question 3: Should I covary s1 and X_moderator? Question 4: At the between level, instead of modeling the relationship between X_within and Y per se, I only allow them to covary. I believe in this way I can have a simpler model, which is more likely to converge. Is it correct?
