lermanIndex: Lerman Index

In partitionComparison: Implements Measures for the Comparison of Two Partitions

Lerman Index

Description

Compute the Lerman index

\frac{N_{11} - E(N_{11})}{\sqrt{\sigma^2(N_{11})}}

Usage

lermanIndex(p, q, c = NULL)

## S4 method for signature 'Partition,Partition,missing'
lermanIndex(p, q, c = NULL)

## S4 method for signature 'Partition,Partition,PairCoefficients'
lermanIndex(p, q, c = NULL)

Arguments

p	The partition P
q	The partition Q
c	PairCoefficients or NULL

Methods (by class)

• lermanIndex(p = Partition, q = Partition, c = missing): Compute given two partitions

• lermanIndex(p = Partition, q = Partition, c = PairCoefficients): Compute given the partitions and pair coefficients
