Where do networks come from?

The key assumption underlying both the peer effects and structural approaches to network effects assume some degree of exogeneity in the existence … More

Analyzing Networks in R: Centrality and Graphing

One important procedure in network analysis is determining the centrality of a node within a social network. In this post, I will show you how to do four things: Calculate four centrality measures Closeness centrality Betweenness centrality Degree centrality (indegree and outdegree) Eigenvector centrality Symmetrize social networks Plot social networks using the gplot function in R. Correlate […]
