Figure 1.

ROC curve comparing step 3 options based on control data sets. The x-axis is the percentage of false positives (FalsePos) and the y-axis is the percentage of true positives (TruePos). The step 3 options described in the text are CV (thresholding of the coefficient of variation), KS (Kolmogorov-Smirnov test), WS (Wilk-Shapiro test) and WKS (weighted Kolmogorov-Smirnov test).
