Finding Statistically Significant Communities in Networks
The score is the -th smallest score of the external vertices. In this particular case there are external vertices. In the figure, we plot , , , , (from left to right). As an example, the shaded areas show the cumulative probability for a few values of that would correspond to the values estimated in a practical situation. In this case, the black area, , is the least extensive and so . If , the vertices with scores , , and will be added to .
