| Nov 16, 2015 at 9:09 | comment | added | Stuart Lacy | In survival models I get different scores from the concordance and the AUC, for instance the different implementations of AUC in the survAUC package linked in the question provide different answers to the concordance. In addition, Heagerty's AUC calculates the AUC across survival probabilities at a specific time threshold, while the concordance is typically calculated of the linear predictors (i.e. time isn't considered) | |
