If I have a data like this:
data sample;
input class x;
datalines;
1 1
1 2
2 1
2 2
2 3
3 5
3 6
run;
And I want the output to be:
class x
1 3
1 4
2 4
2 5
2 6
3 7
3 8
I can get the max number from each class but I don't know how to proceed to the next step by increasing them by 1.
proc sql;
select max(x) into :max_val
from sample
group by class;
quit;
proc means data=sample noprint NWAY;
class class;
var x;
output out=maxes N=N Max = Max;
run;
data want;
set maxes;
do i=1 to n;
x = max + i ;
output;
end;
keep class x;
run;
