It should be possible to calculate the significance of a single ROC curve.

This would test H_0: AUC = 0.5.

For a full AUC this should correspond to the Wilcoxon Test. For partial AUC we need to use bootstrapping. Something like this:

roc.test(roc(aSAH$outcome, aSAH$ndka))
roc.test(roc(aSAH$outcome, aSAH$ndka, partial.auc = c(1, 0.9)))
