KendalTauCoefficients
[this page | pdf | back links]
Function Description
Returns an array of
elements corresponding
to the elements of the matrix,
, formed by Kendal tau coefficients for
each pairing of
series that are
provided to the function as an array of
elements, where the
first
elements correspond to
the terms in the first series, the next
elements to the
corresponding terms in the second series etc.
If
are a set of joint
observations from two random variables
and
then
pairs
and
are
said to be ‘concordant’ if both
and
(or if both
and
). They are said to be
‘discordant’ if
and
or if
and
. Then the elements of
the matrix are as follows, where each entry separately considers all possible
pairs of
for
,
and


N.B. There are various possible approaches to ties. The one
implemented here reduces the denominator so that we still have
and
in the presence of ties,
can take either
extreme value in some circumstances.
