The area under the curve is calculated using the trapezoidal rule. The argument
fpr is the grid on which the (S)ROC curve is evaluated. In many cases the default grid will contain points on which the SROC curve can only be calculated by extrapolation; however if only a subinterval is specified a partial AUC is calculated and the AUC value might differ substantially.
phm objects the AUC and its confidence interval is calculated analytically, for
