s14: 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.

Value

The $S_{14}$ similarity index.

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.
