QuickCons {ConsRank}R Documentation

Quick algorithm to find up to 4 solutions to the consensus ranking problem

Description

The Quick algorithm finds up to 4 solutions. Solutions reached are most of the time optimal solutions.

Usage

QuickCons(X, Wk = NULL, FULL = FALSE, PS = FALSE)

Arguments

X

A N by M data matrix in which there are N judges and M objects to be judged. Each row is a ranking of the objects which are represented by the columns. Alternatively X can contain the rankings observed only once in the sample. In this case the argument Wk must be used

Wk

Optional: the frequency of each ranking in the data

FULL

Default FULL=FALSE. If FULL=TRUE, the searching is limited to the space of full rankings.

PS

Default PS=FALSE. If PS=TRUE the number of evaluated branches is diplayed

Details

This function is deprecated and it will be removed in the next release of the package. Use function 'consrank' instead.

Value

a "list" containing the following components:

Consensus the Consensus Ranking
Tau averaged TauX rank correlation coefficient
Eltime Elapsed time in seconds
