چکیده
Social forces connect individuals in different ways. When individuals get connected, one can observe distinguishable patterns in their connectivity networks. One such pattern is assortativity, also known as social similarity. Assortativity In networks with assortativity, similar nodes are connected to one another more often than dissimilar nodes. For instance, in social networks, a high similarity between friends is observed. This similarity is exhibited by similar behavior, similar interests, similar activities, and shared attributes such as language, among others. In other words, friendship networks are assortative. Investigating assortativity patterns that individuals exhibit on social media helps one better understand user interactions. Assortativity is the most commonly observed pattern among linked individuals. This chapter discusses assortativity along with principal factors that result in assortative networks. Many social forces induce assortative networks. Three common forces are influence, homophily, and confounding. Influence is the process by which Influence,

An Actor-Based Model of Social Network Influence on Adolescent Body Size, Screen Time, and Playing Sports
Recent studies suggest that obesity may be "contagious" between individuals in social networks. Social contagion (influence), however, may not be identifiable using traditional statistical approaches because they cannot distinguish contagion from homophily (the propensity for individuals to select friends who are similar to themselves) or from shared environmental influences. In this paper, we ...
متن کاملCan longitudinal generalized estimating equation models distinguish network influence and homophily? An agent-based modeling approach to measurement characteristics
BACKGROUND Connected individuals (or nodes) in a network are more likely to be similar than two randomly selected nodes due to homophily and/or network influence. Distinguishing between these two influences is an important goal in network analysis, and generalized estimating equation (GEE) analyses of longitudinal dyadic network data are an attractive approach. It is not known to what extent su...

متن کاملHomophily or Influence? An Empirical Analysis of Purchase within a Social Network
Consumers that are close to one another in a social network are known to have similar behaviors. The focus of this study is the extent to which such observed similarity is driven by homophily or social influence. Homophily refers to the similarity in product preferences between individuals who are connected. Social influence is the dependence of consumers’ purchase decisions on their communicat...
متن کاملRuling out latent homophily in social networks
Despite recent high profile studies identifying counter-intuitive behaviors (e.g. obesity [3]) as being socially contagious, Shalizi and Thomas [12] have demonstrated that homophily on latent attributes is indistinguishable from influence. For sociologists to unequivocally identify influence effects in networks they must rule out the possibility of latent homophily as an explanation. This requi...
