Harrell's C and Somers'D statistics

Logistic C(oncordance) statistics (ROC analysis) are classically used to evaluate diagnostic performance. Harrell's C Statistics and Somers'D are concordance statistics adapted to time-dependent models like survival Cox models. They are useful to assess and compare the predictive performance of prognostic scores based on Cox models. It would be great if Xlstat could compute these indices.
