Figure 7.7: Left: ROC curve of a probe set that separates well between BCR/ABL positive and negative tumors. The (total) area under the curve (AUC) is the area of the region surrounded by the x-axis, the line x=1, and the plotted curve. The partial area under the curve (pAUC) for p=0.2 is the shaded area surrounded by the x-axis, the line x=0.2, and the curve. Right: The probe set's data, sorted and colored by the value of the molecular subtype.
