Hello,
Codes for find 20%, 40%, 60%, and 80% percentile for the variable PCR_URINE_COMBINED.
proc univariate data=PROJECT.PAPER_CRIC; var PCR_URINE_COMBINED; output out=perc pctlpre=P_ pctlpts= 20 40 60 80; run;
But how to define tertiles, I did not figure out. Can someone help me? Thank you.
proc univariate data=PROJECT.PAPER_CRIC; var PCR_URINE_COMBINED; output out=tert tertpre=T_ tertpts= 30 60 90; run;
use the option in PROC UNIVARIATE
pctlpts=33.33 66.67
Thank you so much for your help.
