In partitionComparison: Implements Measures for the Comparison of Two Partitions

Peirce Index

Description

Compute the Peirce index

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

Usage

peirce(p, q)

## S4 method for signature 'Partition,Partition'

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

Arguments

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

Methods (by class)

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

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