Parameters: GNetworkX … WebCorrelation coefficient and nestedness in random networks. (Panel A): Correlation coefficient, r, and nestedness g for 106 networks generated independently using the configuration model with N~50 nodes and vkw~5 and (from left to right) scale-free (with exponent c~2:25), Poissonian, and Gaussian (s2 ~10) degree distributions.
Network assortativity coefficient
Did you know?
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.

WebDefinition. Most social, biological, and technological networks display substantial non-trivial topological features, with patterns of connection between their elements that are neither purely regular nor purely random. Such features include a heavy tail in the degree distribution, a high clustering coefficient, assortativity or disassortativity among …
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 …
