Visualization of the empirical log-p-values from p53 dataset for the top-40 classes of each scoring function. Part A shows the results when all class randomizations are normalized and pooled. Part B shows the results when each class is analyzed separately. Different functions are marked similarly to earlier figure. Notice that GSZ-score shows here a clear separation from the other methods in upper plot. In the lower plot it is the best performing method at top ranks and then as signal levels drops GSZ drops to 2ndbest.
