WebThere is an extensive literature on extremization of assortativity over di er-ent graph classes; this section brie y covers the most pertinent points of this literature, focusing on the distinctions between the work presented in this paper and the prior work. Assortativity. Newman [1] introduced (graph) assortativity which is denoted 2[ 1;+1]. WebApr 30, 2024 · Coef(-1, 4) means in the ergm formula a coefficient of -1 on the edges which keeps the graph density down, and a coefficient of 4 on homophily for the "class" variable which means most edges will occur between the 1's or …

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 … See more The basic structure of a network can cause these measures to show disassortativity, which is not representative of any underlying assortative or disassortative … See more The properties of assortativity are useful in the field of epidemiology, since they can help understand the spread of disease or cures.

WebIn graph theory the conductance of a graph G = (V, E) measures how "well-knit" the graph is: it controls how fast a random walk on G converges to its stationary distribution.The conductance of a graph is often called the Cheeger constant of a graph as the analog of its counterpart in spectral geometry.
