Status Centrality


Status centrality is a centrality measure inspired by Katz's status index for sociometric analysis (Katz 1953). It assigns larger scores to vertices whose positions in the graph make them more prominent under the chosen status model. It is used for ranking actors in sociometric data when status can be inherited through chains of relationships rather than only through direct ties. In the Wolfram Language convention, an unnormalized status vector x satisfies

 x=alphaA^(T)x+alphabeta,

where A is the adjacency matrix, beta is the vector of vertex in-degrees, and alpha is a graph-determined attenuation factor. This makes status centrality a Katz-type recursive prestige score with a fixed in-degree baseline. Isolated vertices are assigned status centrality 0.

Status centrality is implemented in the Wolfram Language as StatusCentrality[g], and precomputed values for named graphs can be requested using GraphData[graph, "StatusCentralities"].
