attribute_mixing_matrix(G, attribute, nodes=None, mapping=None, normalized=True)[source]

Returns mixing matrix for attribute.

Parameters
  • G (graph) – NetworkX graph object.

  • attribute (string) – Node attribute key.

  • nodes (list or iterable (optional)) – Use only nodes in container to build the matrix. The default is all nodes.

  • mapping (dictionary, optional) – Mapping from node attribute to integer index in matrix. If not specified, an arbitrary ordering will be used.

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

Returns

m – Counts or joint probability of occurrence of attribute pairs.

Return type

numpy array
