NETWORK > CENTRALITY >FRAGMENTATION

PURPOSE Calculates the fragmentation centrality and distance weighted fragmentation of a binary network.

DESCRIPTION Fragmentation is the proportion of pairs of nodes that cannot reach each other. Distance weighted fragmentation is one minus the average reciprocal distance between all pairs of nodes. Node level fragmentation are these values that involve the specified node. Fragmenetation centrality of a node is the difference in the total score with the node and the score with the node removed. The same process is used for distance weighted fragmentation.

Input network:
Name of file containing network to be analyzed. Data type:Digraph

Output measures: (Default=Fragementation)
Name of UCINET file contating centrality results for the rows

Method
Choices are removal that deletes the node or isolation which removes all the edges incident to the node.
