getphi: Skew-symmetry index - Phi -

In DLEIVA/DyaDA: Dyadic Data Analysis

Description

Function to obtain the skew-symmetry index by means of the observed sociomatrix.

Usage

   getphi(X)

Arguments

X	Original sociomatrix

Details

getphi is only applied for square matrices in which the set of n actors is also the set of n partners.

Value

phi	The skew-symmetry index is based on dyadic discrepancies. The index is the ratio between the sum of squared values due to the skew-symmetrical part and the total sum of squared values.It ranges from 0 to 0.5 and it is a measure of social reciprocity.
