Fig. 3From: On the use of receiver operating characteristic curve analysis to determine the most appropriate p value significance thresholdThe amount of weighted error (Eq. 1) associated with each t cut-off value in our example. The minimum weighted error corresponds to a t value of 1.81 derived by Eq. 22 (the vertical solid red line), corresponding to a p value of 0.036 in our example; the error corresponding to a conventional p significance threshold of 0.05 (the vertical dashed line) is largerBack to article page
