The Clustering Coefficient
Learn about the clustering coefficient metric and how to assess network connectivity and clustering.
The clustering coefficient is a metric that doesn’t try to measure the centrality of a node. Instead, it aims to estimate the degree to which nodes of the network tend to cluster together.
The global clustering coefficient: Transitivity
The global clustering coefficient tries to summarize the degree of aggregation of the network with a single number. One of its names is the transitivity of the network.
Its main idea is to measure the number of triplets of the network. A triplet is a set of three nodes that are connected by either two or three edges.
When these nodes are connected by two edges, we call it an open triplet, such as the following:
