I am trying to carry observations foreward in observations where "number" is three or below. I want to create a new column where observations have been carried foreward and summed, so values in "new_number" are all above three.
HAVE
Age Number
20 10
21 2
22 5
23 1
24 1
25 5
WANT
Age Number New_number
20 10 10
21 2 .
22 5 7
23 1 .
24 1 .
25 5 7
One way:
data want;
set have;
running_total + number;
if running_total > 3 then do;
new_number = running_total;
running_total = 0;
end;
drop running_total;
run;
