WebApr 14, 2016 · The assortativity function from igraph gives you the correlation between knn(k) and k, which is slightly negative in this case (-0.16) considering its values can range from 0 to 1. The knn function gives you the knn only, not k. WebMar 26, 2015 · Degree assortativity is extensively used in network science. Since degree assortativity alone is not sufficient as a graph analysis tool, assortativity is usually combined with other graph metrics. Much of the research on assortativity considers undirected, non-weighted networks. The research on assortativity needs to be extended …
