# attribute_assortativity_coefficient¶

attribute_assortativity_coefficient(G, attribute, nodes=None)

Compute assortativity for node attributes.

Assortativity measures the similarity of connections in the graph with respect to the given attribute.

Parameters : G : NetworkX graph attribute : string Node attribute key nodes: list or iterable (optional) Compute attribute assortativity for nodes in container. The default is all nodes. r: float Assortativity of graph for given attribute

Notes

This computes Eq. (2) in Ref. [R145] , trace(M)-sum(M))/(1-sum(M), where M is the joint probability distribution (mixing matrix) of the specified attribute.
