Correlation (r) between the unweighted and the weighted indices of clustering coefficient.

<p>, and are the clustering coefficient indices proposed by <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0088669#pone.0088669-Watts1" target="_blank">[25]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0088669#pone.0088669-Onnela1" target="_blank">[31]</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0088669#pone.0088669-Zhang1" target="_blank">[9]</a>, respectively. , and are the corresponding signed indices. and are unweighted because they do not depend on edge weights and require a binary network, whereas , , and consider edge weights. The correlations are shown as a function of the threshold used for the dichotomization of the network to compute and .
