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
