Graph assortativity
WebReturns the assortativity of the graph based on vertex categories. Assuming that the vertices belong to different categories, this function calculates the assortativity coefficient, which specifies the extent to which the connections stay within categories. The assortativity coefficient is one if all the connections stay within categories and ... WebAssortativity measures the similarity of connections in the graph with respect to the given numeric attribute. Parameters ---------- G : NetworkX graph attribute : string Node attribute key. nodes: list or iterable (optional) Compute numeric assortativity only for attributes of nodes in container. The default is all nodes.

In the study of complex networks, assortative mixing, or assortativity, is a bias in favor of connections between network nodes with similar characteristics. [1] In the specific case of social networks, assortative mixing is also known as homophily. The rarer disassortative mixing is a bias in favor of connections between dissimilar nodes.
