CLM: Circular Local Minimization

Description

This function computes the Circular Local Minimization.

Usage

CLM(data, order0, ws=NULL, control.method=c("msce","cirktau"))

Value

This function returns a list with the next elements:

order0

the initial order introduced in the arguments.

msce0

the mean sum of circular errors of the initial order with the data.

or itemtau0the mean circular Kendall Tau of the initial order with the data.

final_order

the final order after proccess the Circular Local Minimization.

bestsce

the msce of the final order with the data.

or

bestau

the mean circular Kendall Tau of the final order with the data.

Arguments

data

matrix of circular data to be processed.

order0

the initial order to be improved.

ws

the weights.

control.method

by default "msce", maximization of "cirktau".

Details

This function computes the Circular Local Minimization of the MSCE by default. It computes the Circular Local Maximization of the Circular Kendall Tau if control.method="cirktau".
