Calculates common social network measures on each selected input network.

Analysis for the Meta-Network

Individual entity classes have been combined into a single class, and all networks are combined to create a single network. If two networks connect the same entities, e.g. two agent x agent, then the links are combined. Link weights are made binary.

Key nodes

In-degree centrality

The In Degree Centrality of a node is its normalized in-degree.

Input network(s): meta-network

RankValueUnscaledNodes
100All nodes have this value

Out-degree centrality

The Out Degree Centrality of a node is its normalized out-degree.

Input network(s): meta-network

RankValueUnscaledNodes
100All nodes have this value

Total degree centrality

The Total Degree Centrality of a node is the normalized sum of its row and column degrees.

Input network(s): meta-network

Input network size: 232

Input network density: 0

Expected value from a random network of the same size and density: 0

Eigenvector centrality

Calculates the principal eigenvector of the network. A node is central to the extent that its neighbors are central.

Input network(s): meta-network

Input network size: 232

Input network density: 0

Expected value from a random network of the same size and density: 0.209679

* Number of standard deviations from the mean if links were distributed randomly
Mean: 0.209679
Std.dev: 0.178546

Betweenness centrality

The Betweenness Centrality of node v in a network is defined as: across all node pairs that have a shortest path containing v, the percentage that pass through v.

Input network(s): meta-network

Input network size: 232

Input network density: 0

Expected value from a random network of the same size and density: 0.0220367

RankValueUnscaledNodesContext*
100All nodes have this value
* Number of standard deviations from the mean if links were distributed randomly
Mean: 0.0220367
Std.dev: 0.155743

Closeness centrality

The average closeness of a node to the other nodes in a network. Loosely, Closeness is the inverse of the average distance in the network between the node and all other nodes.

Input network(s): meta-network

Input network size: 232

Input network density: 0

Expected value from a random network of the same size and density: -0.0105117
