networkx.algorithms.mixing.degree_pearsonr

networkx.algorithms.mixing.degree_pearsonr(G)

Compute degree assortativity of graph.

Assortativity measures the similarity of connections in the graph with respect to the node degree.

Parameters :

G : NetworkX graph

Returns :

r : float

Assortativity of graph by degree.

Notes

This calls scipy.stats.pearsonr().
