persistence

persistence(communities, calc='global')[source]

Persistence is the proportion of consecutive time-points that a temporal community is in the same community at the next time-point

Parameters:

  • communities (array) – temporal communities of type: node,time (singlelabel) or node,node,time (for multilabel) communities

  • calc (str) – can be ‘global’, ‘time’, or ‘node’

Returns:

persit_coeff – the percentage of nodes that calculate the overall persistence (calc=global), or each node (calc=node), or for each time-point (calc=time)

Return type:

array
