EdgeWeight
[Optional] Specify the name of the Edges table column that contains the edge weights. The edge weights must be positive values.
Default behavior: The graph is unweighted.
Family
[Optional] Specify the centrality formula:
  • 'eigenvector' (Default)
  • 'katz'
  • 'bonacich'

For descriptions of the centrality formulas, see Centrality Formulas.

Alpha
[Optional] Specify the alpha value for the Katz or Bonacich centrality formula.
Default: 0.85
Beta
[Optional] Specify the beta value for the Katz or Bonacich centrality formula.
Default: 1 for Katz and 0 for Bonacich
Directed
[Optional] Specify whether the graph is directed.
Default: 'true'
MaxIterNum
[Optional] Specify the maximum number of iterations for the function.
Default: 20
StopThreshold
[Optional] Specify the threshold for convergence (the difference of between bk+1 and bk).
Default: 0.001
Accumulate
[Optional] Specify the names of the Vertices columns to copy to the output table.
