Assembly:

Syntax Remarks
Tau-b statistic, unlike tau-a, makes adjustments for ties and
is suitable for square tables. Values of tau-b range from −1
(100% negative association, or perfect inversion) to +1 (100%
positive association, or perfect agreement). A value of zero
indicates the absence of association.
