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
