Concordance probability is commonly used to quantify the predictive accuracy of a marker. Estimators of concordance probability are well studied for binary outcomes but their extensions to censored data have been problematic. In this talk, we will propose an estimator based on the Kaplan-Meier estimate of the survival function and explore its properties. Colorectal cancer staging will be used as an example for illustration.
