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;
