Network assortativity coefficient
Assortativity, or assortative mixing, is a preference for a network's nodes to attach to others that are similar in some way. Though the specific measure of similarity may vary, network theorists often examine assortativity in terms of a node's degree. The addition of this characteristic to network models more closely … See more Assortativity is often operationalized as a correlation between two nodes. However, there are several ways to capture such a correlation. The two most prominent measures are the assortativity coefficient and the neighbor … See more The assortative patterns of a variety of real world networks have been examined. For instance, Fig. 3 lists values of r for a variety of networks. Note that the social networks (the first five entries) have apparent assortative mixing. On the other hand, the … See more • Assortative mixing • Preferential attachment • Homophily • Structural cut-off • Rich-club coefficient See more The properties of assortativity are useful in the field of epidemiology, since they can help understand the spread of disease or cures. For instance, … See more The basic structure of a network can cause these measures to show disassortativity, which is not representative of any underlying … See more WebJan 27, 2016 · Network connections have been shown to be correlated with structural or external attributes of the network vertices in a variety of cases. Given the prevalence of this phenomenon network scientists have developed metrics to quantify its extent. In particular, the assortativity coefficient is used to capture the level of correlation between a single …

Web% assortativity coefficient indicates that nodes tend to link to other % nodes with the same or similar degree. % % Inputs: CIJ, binary directed/undirected connection matrix % flag, 1 = directed graph; 0 = non-directed graph % % Outputs: r, assortativity % % Notes: The function accepts weighted networks, but all connection % weights are ignored. WebThe assortativity coefficient measures the level of homophyly of the graph, based on some vertex labeling or values assigned to vertices. If the coefficient is high, that means that connected vertices tend to have the same labels or similar assigned values. M.E.J.
