consistencyRatio-methods: Function to determine Consistency Ratio
In FuzzyAHP: (Fuzzy) AHP Calculation

Description Usage Arguments Details Value

This methods calculates Consistency Ratio for PairwiseComparisonMatrix. The consistency ratio can only be provided for PairwiseComparisonMatrix with less than 10 rows. For bigger matrices the value is not known.

consistencyRatio(comparisonMatrix, print.report = TRUE)

## S4 method for signature 'PairwiseComparisonMatrix'
consistencyRatio(comparisonMatrix, print.report = TRUE)

## S4 method for signature 'FuzzyPairwiseComparisonMatrix'
consistencyRatio(comparisonMatrix, print.report = TRUE)

`comparisonMatrix`	A `PairwiseComparisonMatrix`
`print.report`	Optional boolean parameter stating if short report should be printed along with determination of Consistency Ratio. Default value is `TRUE`.

Generally pairwise comparison matrixes are considered to be consistent if the value of Consistency Ration is smaller than 0.1. For matrices comparing more then 10 elements then Consistency Ratio is unsuitable, because the values of random index, that is necessary to obtain Consistency Ratio, are only known for matrixes with size smaller than 10\times10.

A numeric value of Consistency Ratio, for PairwiseComparisonMatrix with more than 10 an error is raised.
