This view can be used to show statistical analysis of a network.

The user interface

To calculate network statistics select a network in the datamanager. At this time the following statistics are calculated for the entire network:

• The number of vertices in the network
• The number of edges in the network
• The number of edges which have the same vertex as beginning and end point
• The average degree of the nodes in the network
• The connection density the network (the number of edges divided by the number of possible edges)
• The unweighted efficiency of the network ( 1 divided by average path length, this is zero for disconnected graphs)
• The global clustering

Furthermore some statistics are calculated on a per node basis and displayed as histograms:

• The degree of each node
• The (unweighted) betweenness centrality of each node
• The spread of shortest paths between each pair of nodes (For disconnected graphs the shortest paths with infinite length are omitted for readability)
