bestPermutation: Function to obtain the best permutation for a classification...

In cwm: Cluster Weighted Models by EM algorithm

Description

When a classificator is run on a set of 1,2,..., k groups it returns a possibile classification schemes, but it does not know the correspondence of original gruoups and given groups. This function return the permutation of original group versus output group that maximizes the trace of the confusion matrix.

Usage

bestPermutation(origClass, inizOutput)

Arguments

origClass	original group identification vector
inizOutput	classified group identification vector

Details

Program fails if number of original groups differs from identified groups as in inizOutput.

Value

An object of class bestPermutation containing:

permutation	Best permutation
groups	Classification with respect to best permutation

Note

Shall be improved
