Subject: [R-meta] Moderators: Center then separate or vice versa
Hello All,
(1) I want to center my continuous *time* moderator (*time* -->
*time_c*) so as to make my intercept meaningful.
(2) Because *time* varies both within and between studies, I want to
separate the within (*time_within*) and between part of time
(*time_between*).
I was wondering if I could do both these steps together? If yes,
should I first do (1) and then do (2) or vice versa?
Have a blessed weekend,
Fred
