Selected network indices for evaluation.

Level	Metrics	Formulation	Definition
Node-level	degree centrality		The number directly linked to the nodes
	Average distance		The average length of path starting from given node
Network-level	Density		The ratio between actual edges and potential edges in a network
	Average degree		The average of degree centrality in the network
	Diameter		The length of longest path in network
	Effective size		The average nonredundancy score of all the primary alters
