In seekme94/influence.mining: Provides various methods for influence mining on Graphs
katz_centrality R Documentation
Calculates Katz centrality (Katz Status Index) of network. Original implementation has been modified to escape the invalid alpha value error which happens when a graph is not acyclic
Description
Katz centrality computes the relative influence of a node within a network by measuring the number of the immediate neighbors (first degree nodes) and also all other nodes in the network that connect to the node under consideration through these immediate neighbors
Usage
katz_centrality(graph, alpha = 0.1)
Arguments
graph
The input graph as igraph object
alpha
The alpha parameter, which must be between 0.0-0.2. The default is 0.1.
vids
Vertex sequence, the vertices for which the centrality values are returned. Default is all vertices.
Value
A numeric vector contaning the centrality scores for the selected vertices.
