MARIraw: raw Modified Adjusted Rand Index

In aricode: Efficient Computations of Standard Clustering Comparison Measures

raw Modified Adjusted Rand Index

Description

A function to compute a modified adjusted rand index between two classifications as proposed by Sundqvist et al. in prep, based on a multinomial model. Raw means, that the index is not divided by the (maximum - expected) value.

Usage

MARIraw(c1, c2)

Arguments

c1	a vector containing the labels of the first classification. Must be a vector of characters, integers, numerics, or a factor, but not a list.
c2	a vector containing the labels of the second classification.

Value

a scalar with the modified ARI without the division by the (maximum - expected)
