Subject: random sampling from existing data
I want to do random data checking for a big date set. The total sample is
20,000, and I need randomly pick up 100 from them, I remember it's
something to do with rununi, somehow, I couldn't get it by search SAS menu.
can someone give me a quick guidance?
Thanks in advance.
