Statistical evaluation of the difference between the true and false positives data sets. The difference between the average Poccupied of the false positives and true positives set is plotted in blue. The maximal difference (0.2) is observed for α = 0.01. For each data point in the graph, a Welch two-sample t-test was performed on the data sets to assess the statistical significance of the difference in their mean Poccupied values. The obtained p-values were plotted in red. The difference in mean between the true and false positives data sets is most significant for α = 0.01 (p-value = 8.46e-9).
