Fig. 4

ROC and PR curves for Jacobian determinant maps with time spans in the range 2.5 < Δt < 3.5 years using 0.5% of the features. On the left, the ROC curve is averaged across different development/test splits: the mean curve (blue) with the standard deviation (gray) and the curve of a random classifier (red). On the right, the PR curve of the classifier (blue) is overlaid on a savings heatmap (Eq. 1). Black lines indicate points of equal savings
