goodmanKruskal: Goodman & Kruskal Index

Description

Compute the index of Goodman and Kruskal $$\frac{N_{11}N_{00} - N_{10}N_{01}}{N_{11}N_{00} + N_{10}N_{01}}$$

Usage

goodmanKruskal(p, q)
# S4 method for Partition,Partition
goodmanKruskal(p, q)
# S4 method for PairCoefficients,missing
goodmanKruskal(p, q)

Arguments

p

The partition \(P\) or an instance of '>PairCoefficients

q

The partition \(Q\) or NULL

Methods (by class)

• p = Partition,q = Partition: Compute given two partitions

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