I am analyzing data from a diary study (multilevel modeling), and I want to person-mean center my variables using Mplus. One of my variables is inclusion climate (IC) which was measured on four days from the same participants. How do I compute person-centered averages in Mplus? Can experts here suggest steps or syntax for the same?
Following this, I am planning to compute intraclass coefficients ICC using Mplus. Can anyone suggest steps to take to proceed?
