centr_lev | R Documentation |
Calculates the leverage centrality of each vertex in a graph.
centr_lev(g, A = NULL)
g |

A |
Numeric matrix; the adjacency matrix of the input graph. Default:

The leverage centrality relates a vertex's degree with the degree of its neighbors. The equation is:
l_i = \frac{1}{k_i} \sum_{j \in N_i} \frac{k_i - k_j}{k_i + k_j}
where k_i
is the degree of the i^{th}
vertex and N_i
is the
set of neighbors of i. This function replaces NaN with
NA (for functions that have the argument na.rm).
A vector of the leverage centrality for all vertices.
