You can visit that page and Vote on the idea, and add any comments you'd like.

Hi,
I am wondering if there is an option in Proc Phreg to request c-statistics. I know such option exists in Proc Logistic and it is also known as 'concordance' in R 'survival' package. I can find SAS code to computer this but could not find such option in Proc Phreg. I would be surprised if SAS have not implemented it.
Thanks,
Z
