cdlib.evaluation.avg_transitivity

avg_transitivity(graph: <Mock id='139918925505744'>, communities: object, **kwargs) → object

Average transitivity.

The average transitivity of a community is defined the as the average clustering coefficient of its nodes w.r.t. their connection within the community itself.

Parameters:

• graph – a networkx/igraph object
• communities – NodeClustering object
• summary – boolean. If True it is returned an aggregated score for the partition is returned, otherwise individual-community ones. Default True.

Returns:

If summary==True a FitnessResult object, otherwise a list of floats.

Example:

>>> from cdlib.algorithms import louvain
>>> from cdlib import evaluation
>>> g = nx.karate_club_graph()
>>> communities = louvain(g)
>>> scd = evaluation.avg_transitivity(g,communities)
