Hi Folks,
I'm trying to subset data where
1. year(date_diagnosis)=year(claim_date)
and
2. Oct, Nov and Dec of year before and Jan, Feb and Mar of year after the year(claim_date) to account for border months.
Desired output is the data with variable mark (1,0) where 1 indicating the data I'm gonna keep.
Thanks for help. I greatly appreciate your time.
DATA HAVE;
format PAT_ID 1. CLAIM_DATE date9. YEAR 4. MARK 1.;
informat CLAIM_DATE date9. YEAR 4. MARK 1.;
input PAT_ID CLAIM_DATE YEAR MARK;

Would this work:
data want;
set have;
where mdy(10,1,year-1) <= CLAIM_DATE and mdy(3,31,year+1) >= CLAIM_DATE;
