get_leverage_centrality

Get leverage centrality

Description

Get the leverage centrality values for all nodes in the graph. Leverage centrality is a measure of the relationship between the degree of a given node and the degree of each of its neighbors, averaged over all neighbors. A node with negative leverage centrality is influenced by its neighbors, as the neighbors connect and interact with far more nodes. A node with positive leverage centrality influences its neighbors since the neighbors tend to have far fewer connections.

Usage

get_leverage_centrality(graph)

Arguments

graph

A graph object of class dgr_graph.

Value

A data frame with leverage centrality values for each of the nodes.

Examples

# Create a random graph using the
# `add_gnm_graph()` function
graph <-
  create_graph(
    directed = FALSE) %>%
  add_gnm_graph(
    n = 10,
    m = 15,
    set_seed = 23)

# Get leverage centrality values
# for all nodes in the graph
graph %>%
  get_leverage_centrality()

# Add the leverage centrality
# values to the graph as a
# node attribute
graph <-
  graph %>%
  join_node_attrs(
    df = get_leverage_centrality(.))

# Display the graph's node data frame
graph %>% get_node_df()
