The only way I&nbsp; know how is to ods output the 10,000 Hazard Ratio, combine them together then calculate the mean. I am wondering if there is any better ways of doing without outputting every single one of them?</P><P>&nbsp;</P><P>&nbsp;</P> Tue, 13 Nov 2018 21:03:00 GMT https://communities.sas.com/t5/New-SAS-User/Simulation-and-outputs/m-p/512744#M2430 CHELS 2018-11-13T21:03:00Z https://communities.sas.com/t5/New-SAS-User/Simulation-and-outputs/m-p/512753#M2433 <P>Yes. Instead of 10,000 data sets, use one data set with 10,000 values of an ID variable. Use BY group analysis in PROC PHREG and a single ODS OUTPUT statement.
