WebI had been using the formula for calculating the rows of area under the curve at each cut off as described [=(F9-F10)*G9]. However, with some ROC curves, especially it seems where there are groups of results with identical FPR and/or TPR values and I’m calculating the TPR and FPR for very fine increments of cut offs, the sum of those rows over estimates … WebD-prime (signal detection) analysis. 1. Taking response bias into account. The model of discrimination performance discussed in the previous file assumes that when listeners do not hear a difference, or are not sure, they respond "same" or "different" randomly, so that performance is at chance. But there is no guarantee that listeners will do that.
