Percentiles

[Hilde]

Hey there!

What is the best / quickest way to calculate the 75th percentile in SAS from different variables in a very large data set?

Is there a way to only calculate the percentile and not the other statistics in Proc univariate?

Thanks

How about this:

proc summary data = sashelp.class p75 print;

    var age;

run;

But I am not sure it is the quickest.

PROC STDIZE has a one-pass apprach that you may find useful. PCTLMTD=ONEPASS
