Hi SAS users,
I have a dataset with 3 variables: ID, date1 and date2. I would like to create a new dataset that identifies which observations have a date2 that is 5 months or greater than date1. For example using the data below, I would like to identify IDs 7 and 11 as they have a date2 that is at least 5 months greater than date1.
Thanks.
data have;
input id date1 date2;
cards;
5 05/12/2010 06/12/2010
7 06/22/2010 12/30/2010
9 02/04/2009 05/03/2009
11 03/27/2009 11/05/2009
;
run;
try this one:
data have;
informat date1 date2 mmddyy10.;
format date1 date2 mmddyy10.;
input id date1 date2;
cards;
5 05/12/2010 06/12/2010
7 06/22/2010 12/30/2010
9 02/04/2009 05/03/2009
11 03/27/2009 11/05/2009
;
data want;
set have;
if date2>intnx('month',date1,5,'s');
proc print;run;
