Calculate s14 Similarity Index

Description

Computes the S_{14} similarity index between two network matrices.

Usage

s14(d1, d2)

Arguments

d1

An n by n matrix representing a network.

d2

An n by n matrix representing a network.

Details

Given two networks of interest, a common measure of similarity is the S_{14} index introduced by Gower and Lagendre (1986). The function s14 computes this similarity measure for two networks having the same dimensions.

Value

The S_{14} similarity index.
