PLS-DA ROC curve. Schematic Illustration of ROC curves of PLS-DA classification on textural features using CTPA slices from 35 dogs. The green line represents the predicted ROC curve whereas the dark blue line represents the leave-one-dog-out cross-validation ROC curve. The plot in (a) is a plot of test sensitivity (y coordinate) versus its specificity (x coordinate) for the healthy dogs. The plot in (b) is a plot of test sensitivity (y coordinate) versus its specificity (x coordinate) for the diseased dogs with PTE. The plot in (c) is a plot of test sensitivity (y coordinate) versus its specificity (x coordinate) for the diseased dogs without PTE
