MI_simple {bikm1}

MI_simple function for agreement between two partitions

Description

Produce a measure of agreement between two partitions.(between 0 and 1). A value of 1 corresponds to a perfect match.

Usage

MI_simple(v,vprime)

Arguments

v

numeric vector specifying the class of observations.

vprime

numeric vector specifying another partitions of observations.

Value

the value of the index.
