Thank you Mike! I have a question: do I have to center (grand mean or group mean centering) also the outcome variable? Or just the predictors? Thank you in advance

Hello, Thank you for the video. I want to ask how can i do the group mean centering with multiple item scale with repeated measure data. Should i do the centering item-by-item or after calculating the mean of all items?

Hey Mike, thank you for the video. My question is: what if I want to center level two (school) variables? In this case only grand mean center is possible, of course. But should I compute the mean considering (in the denominator) the number of students or the number of schools?
