Dear All,
I am new to the listserv, so I apologize if this has been covered before. I
am trying to create a constant variable for mixed modeling but I can't wrap
my head around solving the issue without copying and pasting (not
feasible).
I would like to recode group membership so that it is the same at time 0
for the rest of the time values for each case. See below for my current
data setup.
Your help is most appreciated!
Sincerely,
Kevin Manning
