PROC RANK

[Sami1234]

Dear All,

Please, can someone guide how can I use proc rank to select the best 10% of the records by each treatment and then apply to proc survey for tipping point analysis?

Thanks

proc rank data=have groups=10;
by treatment;
var myVar;
ranks rankMyVar;
run;

*then select the records where the group=9.

No idea about PROC SURVEY and the tipping point analysis.
