Gower & Legendre Index

Description

Compute the index of Gower and Legendre

\frac{N_{11} + N_{00}}{N_{11} + \frac{1}{2}\left(N_{10} + N_{01}\right) + N_{00}}

Usage

gowerLegendre(p, q)

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

## S4 method for signature 'PairCoefficients,missing'
gowerLegendre(p, q)

Arguments

p

The partition P or an instance of PairCoefficients

q

The partition Q or NULL

Methods (by class)

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

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