Dear all,
I looked into the archives, and still I am not sure how to proceed :
I have a panel dataset (id - day) and I would like to obtain a variable X that keeps the running sum (or the average) of variable Y's observations that occur in a given moving time window : that is between today's observation date and (today's observation date - X) where X is fixed.
Do you know how to proceed ?
Many thanks
