Tau exstension is a new rank correlation coefficient defined by Emond and Mason (2002)
tau_x(X, Y = NULL) Tau_X(X, Y = NULL)
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.
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.
