Leverage Centrality
Definition
Leverage centrality considers the degree of a node relative to its neighbors and operates under the principle that a node in a network is central if its immediate neighbors rely on that node for information.
Leverage centrality is a measure of the relationship between the degree of a given node (ki) and the degree of each of its neighbors (kj), averaged over all neighbors (Ni), and is defined as shown below.
A node with negative
leverage centrality is influenced by its neighbors, as the neighbors
connect and interact with far more nodes. A node with positive
leverage centrality, on the other hand, influences its neighbors
since the neighbors tend to have far fewer connections.
