Fig. (8) Effects of test results on diagnostic information gain. The total information gain IG_T (solid black curve), and the two components in the sum IG_T = IG_R + IGD+ , are shown as a function of the positive likelihood ratio. The range information gain IG_R is the lower red dashed curve, and the disease information gain is the middle blue dashed curve. These curves are computed using the distribution over pre-TP values from Fig. (6C).
