networkx.algorithms.assortativity.degree_mixing_dict

degree_mixing_dict(G, x='out', y='in', weight=None, nodes=None, normalized=False)[source]

Returns dictionary representation of mixing matrix for degree.

Parameters
  • G (graph) – NetworkX graph object.

  • x (string (‘in’,’out’)) – The degree type for source node (directed graphs only).

  • y (string (‘in’,’out’)) – The degree type for target node (directed graphs only).

  • weight (string or None, optional (default=None)) – The edge attribute that holds the numerical value used as a weight. If None, then each edge has weight 1. The degree is the sum of the edge weights adjacent to the node.

  • normalized (bool (default=False)) – Return counts if False or probabilities if True.

Returns

d – Counts or joint probability of occurrence of degree pairs.
