The local clustering coefficient of the blue node is computed as the proportion of connections among its neighbours which are actually realised compared with the number of all possible connections. In the figure, the blue node has three neighbours, which can have a maximum of 3 connections among … See more In graph theory, a clustering coefficient is a measure of the degree to which nodes in a graph tend to cluster together. Evidence suggests that in most real-world networks, and in particular social networks, nodes tend to create … See more The global clustering coefficient is based on triplets of nodes. A triplet is three nodes that are connected by either two (open triplet) or three (closed triplet) undirected ties. A triangle graph therefore includes three closed triplets, one centered on each of the nodes ( See more • Directed graph • Graph theory • Network theory • Network science • Percolation theory • Scale free network See more The local clustering coefficient of a vertex (node) in a graph quantifies how close its neighbours are to being a clique (complete graph). Duncan J. Watts and Steven Strogatz introduced … See more For a random tree-like network without degree-degree correlation, it can be shown that such network can have a giant component, and the percolation threshold (transmission probability) is given by $${\displaystyle p_{c}={\frac {1}{g_{1}'(1)}}}$$, … See more • Media related to Clustering coefficient at Wikimedia Commons See more WebMay 28, 2008 · 3.

Recall that y icjk represents the binary indicator of LOH for SNP k in region j of chromosome c for patient i. Let y icj =(y icjk,1⩽k⩽n icj) be the entire LOH sequence from the jth region for chromosome c of the ith patient.
