Hello,
Simple problem: I need to create a data set in which the maximum value is reported for each categorical variable. For example:
Col1 Col2
a 2
a 1
a 0
b 3
b 0
c 1
c 2
c 3
Would read as follows:
Many thanks!
data have;
input Col1 $ Col2;
cards;
;
proc sql;
create table want as
select col1,max(col2) as col2
from have
group by col1;
quit;
