avg_transitivity(graph: <Mock id='140619399398672'>, 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.

  • 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.

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