There is a SASWare Ballot idea for this here:

PROC PHREG: add survival-based c-statistic

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

How to get c-statistics (c-index, concordance) from Proc Phreg for survival analysis

imcbczm — Wed, 11 Nov 2015 21:04:39 GMT

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,

I don't think there is. PROC PHREG is designed for survival analysis though it can be used for specific types of logistic regression.
