Subject: strange behavior of proc rank
Content-Type: text/plain; charset=ISO-8859-1
It's been a long time since I asked a question last time.
I have seen a very strange behavior of "proc rank ties = low groups = 2".
I have a 2-level numeric variable x with 0 and 1 with a relatively
even freq. distribution. when I applied the above "proc rank ties =
low groups = 2 data = ... out = ...; var x; ranks rank", the variable
"rank" only has 1 level. I could hardly believe what I saw.
Any insight or similar experience?
Thank you so much!
