TABLE I.

Coverage Probabilities and Mean Confidence Interval Lengths Corresponding to 95% Confidence Intervals for AUC_A – AUC_B.The Table Compares Confidence Intervals Based on the Mann-Whitney Statistic (MW) to Intervals Based on $\widehat{\text{SNR}}$. All Coverage Probabilities are Expressed in %
