gammaStatistics: Gamma Statistics

In partitionComparison: Implements Measures for the Comparison of Two Partitions

Gamma Statistics

Description

Compute the Gamma statistics

\frac{N_{11}N_{00} - N_{10}N_{01}}{\sqrt{ N_{21}N_{12}N'_{10}N'_{01} }}

Usage

gammaStatistics(p, q)

## S4 method for signature 'Partition,Partition'
gammaStatistics(p, q)

## S4 method for signature 'PairCoefficients,missing'
gammaStatistics(p, q = NULL)

Arguments

p	The partition P or an instance of PairCoefficients
q	The partition Q or NULL

Methods (by class)

• gammaStatistics(p = Partition, q = Partition): Compute given two partitions

• gammaStatistics(p = PairCoefficients, q = missing): Compute given the pair coefficients
