tna (version 0.4.0)

summary.tna: Calculate Summary of Network Metrics for a Transition Network

Description

This function calculates a variety of network metrics for a tna object. It computes key metrics such as node and edge counts, network density, mean distance, strength measures, degree centrality, and reciprocity.

Usage

# S3 method for tna
summary(object, ...)

Value

A named list containing the following network metrics (invisibly):

  • node_count: The total number of nodes.

  • edge_count: The total number of edges.

  • network_Density: The density of the network.

  • mean_distance: The mean shortest path length.

  • mean_out_strength: The mean out-strength of nodes.

  • sd_out_strength: The standard deviation of out-strength.

  • mean_in_strength: The mean in-strength of nodes.

  • sd_in_strength: The standard deviation of in-strength.

  • mean_out_degree: The mean out-degree of nodes.

  • sd_out_degree: The standard deviation of out-degree.

  • centralization_out_degree: The centralization of out-degree.

  • centralization_in_degree: The centralization of in-degree.

  • reciprocity: The reciprocity of the network.

Arguments

Details

The function extracts the igraph network and computes the following network metrics:

  • Node count: Total number of nodes in the network.

  • Edge count: Total number of edges in the network.

  • Network density: Proportion of possible edges that are present in the network.

  • Mean distance: The average shortest path length between nodes.

  • Mean and standard deviation of out-strength and in-strength: Measures of the total weight of outgoing and incoming edges for each node.

  • Mean and standard deviation of out-degree: The number of outgoing edges from each node.

  • Centralization of out-degree and in-degree: Measures of how centralized the network is based on the degrees of nodes.

  • Reciprocity: The proportion of edges that are reciprocated (i.e., mutual edges between nodes).

A summary of the metrics is printed to the console.
