LUVAIN: Stata module to find communities in weighted graph


  • Nikos Askitas

Programming Language



louvain wraps itself around the Python module "python-louvain" to find clusters in a weighted graph. It assumes you have loaded your network's weighted edges in stata in the form of three variables. So if you have string variables "snode" (the source node) and "tnode" (the target node) and some numerical variable "weight" then you feed the weighted edges by running: louvain snode tnode weight which creates a frame called "louvain" in which it saves two variables: one called "node" holding the unique values of snode and tnode combined and one called "cluster_1" indicating the cluster each node belongs to.
