pairwiseConsistencyMeasures: Consistency Measures for Pairwise Comparison Matrices

Description

This function calculates four pairwise consistency checks: Consistency Ratio (CR) from Saaty (1980), Koczkodaj's Measure from Koczkodaj (1993) and Congruence / Dissonance Measures from Siraj et al. (2015).

Usage

pairwiseConsistencyMeasures(matrix)

Value

The function returns a list of outputs for the four pairwise consistency checks

Arguments

matrix

A reciprocal matrix containing pairwise judgements
