SAS - Large Values · 2008-02-12

Do you know SAS, the business intelligence tool with the 60ies-charmes? If the day comes, when you need to find the first and second largest value from a set of observations, here is how it'd work:

proc summary data=&inputdataset.;
   var &variable.;
   class &class_list.;
      sum=idgroup(max(&variable.) out[2] (&variable.)=)
      /autolabel autoname;

Somehow idgroup and out[2] do the trick. Why it works and what else to look after can be found in "Getting the Most from PROC MEANS" by Andrew H. Karp.
