Hubbell centrality defined as: $$C_{h} = E + WC_{h}$$ where \(E\) is some exogeneous input and \(W\) is a weight matrix derived from the adjancancy matrix \(A\).
hubbell(graph, vids = V(graph), weights = NULL, weightfactor = 0.5)
The input graph as igraph object
Vertex sequence, the vertices for which the centrality values are returned. Default is all vertices.
Possibly a numeric vector giving edge weights. If this is NULL, the default, and the graph has a weight edge attribute, then the attribute is used. If this is NA then no weights are used (even if the graph has a weight attribute).
The weight factorLogical which must be greater than 0. The defualt is 0.5.
A numeric vector contaning the centrality scores for the selected vertices.
This centrality value is defined by means of a weighted and loop allowed network. The weighted adjacency matrix \(W\) of a network G is asymmetric and contains real-valued weights for each edge. More detail at Hubbell Index
