Grouping variables in SAS

n7 — Sun, 07 Jun 2020 01:26:51 GMT

I am trying to find the equivalent of the Stata code "egen group" in SAS. The goal is: I have three variables x, y, and z. I want to create a new variable which will assign a different ordinal number for each combination of values of x, y, and z. How can I do this in SAS?

With hope I understand you correctly, use next code:

proc sort data=have; by x y z; run;
data new;
 set have;
  by x y z;
      retain key;
      if first.z then key+1;
run;
