Sensitivities of the different methods, averaged over the range of perturbations shown in Figure 4, are summarised in Figure 5 for all the methods of assessment. This shows that the Specificity measure with shuffle radius 1.5 or 2.1 is the most sensitive of the measures studied, and that this advantage is statistically significant.
