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 PairwiseComparisonMatrix
consistencyRatio(comparisonMatrix, print.report = TRUE)
# S4 method for FuzzyPairwiseComparisonMatrix
consistencyRatio(comparisonMatrix, print.report = TRUE)
Optional boolean parameter stating if short report should be printed along with determination
of Consistency Ratio. Default value is TRUE.
A numeric value of Consistency Ratio, for '>PairwiseComparisonMatrix with more than 10
an error is raised.
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 \(10\times10\).
