Table 1: Node-based measures of connectivity.
Metric Type Definition
Alpha centrality Indirect Alpha centrality of all vertices. A generalization of eigenvector centrality to directed graphs (Bonanich 2001).
Betweenness centrality Indirect Reflects the amount of control that a node exerts over the interactions of other nodes in the network.
Closeness centrality Indirect A measure of how fast information spreads from a given node to other reachable nodes in the network. The Latora closeness centrality is used in networks with disconnected components (Latora and Marchiori 2001).
Degree centrality Direct The number of edges connected to a node.
Eccentricity centrality Indirect The maximum non-infinite length of a shortest path between n and another node in the network.
