Hi!
I have a dataset where I would like to count the number of times different values of a variable occurs but only once for every Id.
ID Variable
1 A
2 B
3 B
4 A
5 A
1 A
1 B
3 B
4 B
I want this as a result:
Count_A Count_B
3 4
If ID 1 have A twice I only want it to count as one.
Thanks! I didn't quite work.
I used the following code (as I also had to group by other variable)
proc sql;
create table want as
select
year, variable, count(distinct ID)
from data
group by
year, variable
;
quit;
proc sql;
create table want as
select count(distinct id) as Count_A,
count(distinct Variable) as Count_B
from have;
quit;
