Hi,
I have the following dataset
Account ID Month Arrears
1 1 0
1 2 1
1 3 0
1 4 1
1 5 2
1 6 2
1 7 0
and need the foloowing dataset - if arrears gt 0 then count months since last 0 in arrears
Account ID Month Arrears Count
1 1 0 0
1 2 1 1
1 3 0 0
1 4 1 1
1 5 2 2
1 6 2 3
1 7 0 0
Any help to code this scenario would be helpful.
Thanks
Adnan
Try next code:
data want;
set have;
by id;
retain count;
if first.id or arrears=0 then count=0;
else count+1;
run;
