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.

There are several warning and error messages. I will leave them to you.

At least two issues need to be addressed in the moderator analysis. Firstly, the function is unable to recognize "age*TL13". To resolve this, you need to create a new variable, say "age_TL13" in the data frame. Secondly, there are some missing values in TL13, which is not acceptable for moderators.
