Nick,
I have a survey that was conducted over many days
(390) with many interviews each day (58,373 cases
total). So I have a numeric variable "day" (which runs
from 1 to 390) and another numeric variable - campaign
statements (st) - that is daily (see below). I want to
create a new variable (st_7) that is the mean
statements for the prior 7 days. Of course, I want
values for all cases.
Thanks!
James
