Hi.

I have short question.

I am conducting analysis to test whether PSM moderate between TL and JC.

But, my study variables are combined with control variables.

In this situation, when testing the ineraction effect, control variables can be added in level2 slope term?

Or control variable can be added only in level 2 intercept term?

Therefore, what is the appropriate way upper or lower? (upper image or lower image)

What is the appropriate way in conventional multilevel modeling?
