Figure 13From: A survey of results on mobile phone datasets analysis Probability of a new communication to form a new tie. Probability functions \(p_{k}(n)\) calculated for different degree groups. In the inset, symbols show the averaged \(p_{k}(n)\) values for groups of nodes with degrees between the corresponding \(k_{\mathit{min}}\) values.
