In tna: Transition Network Analysis (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 class 'tna'
summary(object, ...)

Arguments

object	A tna object.
...	Ignored.

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.

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.
