Description

Tau exstension is a new rank correlation coefficient defined by Emond and Mason (2002)

Usage

1
Tau_X(X, Y = NULL)

Arguments

X

a M by N 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. If there is only X as input, the output is a square matrix containing the Tau_X rcc.

Y

A row vector, or a n by M data matrix in which there are n judges and the same M objects as X to be judged.
