Thanks a lot for the discussion... sorry that I'm a little late getting back into the game.
From what I gleamed, I'm not totally sure that I 100% got across what we are looking for. We are looking for a single correlation coefficient which correlates VAR 1 vs VAR 2 across all the time points (with only M and SD).
(Var 1 time 1 + Var 1 time 2 + Var 1 time 3) correlated with (Var 2 time 1 + Var 2 time 2 + Var 2 time 3)
In other words, trying to somehow bring together the different time points while correlating VAR 1 and VAR 2.
I've been skimming a lot of resources, but nothing seems to come close to what we are looking form. Perhaps this is the end of line
