Dear Dr. Cheung and Colleagues,
I attempted to include an interaction term and other moderators in a path model.
However, it produced unusual estimates and the following message: "The model does not satisfy the first-order optimality conditions to the required accuracy, and no improved point for the merit function could be found during the final linesearch (Mx status RED)."
Could you please provide me with some suggestions?
I have attached the R code and the dataset.
Thanks for your time and patience.
