Hi,
I have following data
obs | A | B | C | D |
1 | Type 1 | B1 | C1 | 1 |
2 | Type 1 | B1 | C2 | 3 |
3 | Type 2 | B2 | C3 | 2 |
4 | Type 3 | B3 | C4 | 5 |
I need a list (proc print or proc repot) like below. The “summary” line should show number of unique observations for variable A, B and C as well as SUM value for variable D.
A | B | C | D |
Type 1 | B1 | C1 | 1 |
Type 1 | B1 | C2 | 3 |
Type 2 | B2 | C3 | 2 |
Type 3 | B3 | C4 | 5 |
3 | 3 | 4 | 11 |
Below simple code get me a little bit forward:
proc print data=test noobs;
var A B C D;
sum D;
run;
But what do I do for A, B and C? I need the number of unique observations for variable A, B and C.
Is this possible with proc print or proc report?
Thanks
Sure .

To get count of unique values you'll need at least one other step. Proc freq or proc means with levels or Proc SQL and select distinct can get the counts of unique values. Proc freq may be the best bet:
I see how you get all the numbers in your chart except for the count of 5 in the column for C...it looks like the number at the bottom of the report should be 4 for C??

Hi Cynthia,
Yes, the number count for C should be 4.
Is it possible to use compute in proc report to get the count?
Sure .
