| Abstract: | Receiver operating characteristic (ROC) curves for the detection of Poisson distributed signals were evaluated by computer simulation and found to be a set of nearly collinear points when plotted on probability axes. Approximate expressions were derived for the slope and intercept (d ) of the line containing the points. The predictive value of these expressions was verified by measuring slopé and d of ROC curves produced from computer simulation of Poisson signals. Estimates of slope and d from empirical ROC curves were distributed according to the Gaussian probability density with variance approximately equal to 3/n, where n is the number of stimulus repetitions used to determine the ROC. |
