Prism's calculations of area under the curve are very simple, as explained here. Area under what curve? This page is about Prism's analysis named "Area under the curve". Prism has a separate analysis to create a Receiver Operator Characteristic (ROC) curve and this analysis also c...
Area under the predictiveness curve and proportion of cases explained.HonCheong, SoPak, C. Sham
The area under the ROC curve, or AUC, is one of the most popular classifier evaluation metrics for static imbalanced data [31]. Its basic interpretation and calculation procedure can be explained by analyzing the way in which ROC curves are created. If we denote examples of two classes distin...

the area under the ROC curve while replacing the 0–1 loss function with a smooth surrogate function. The constrained threshold gradient descent regularization algorithm was applied, where the regularization parameters were chosen by the cross-validation method, and the confidence intervals of the ...
(d) Granger-causality analysis of the mean firing rate revealed an asymmetric directionality from the VTA to the PFC. Only the GCI for the pDA group is statistically different from the expected GCI under the hypothesis of no temporal structure. This suggests that pDA neurons (not Non-DA ...

In addition to the area under the curve, in line with Rittger et al., 2013, Masson et al., 2018, we also calculate the F-score which is the harmonic mean of the positive predictive value and the true positive rate, where a score of F = 1 is perfect and F = 0 is the worst ...
pattern. As far back as the 1800s, the species area curve has been used to describe this relationship (Rosenweig 1995). Today, the species area curve has several applications. It may be used to compare species diversities of different communities. It is also used to determine the ...
