sequence of paired numbers: (L(k,i), R(k,i)) for k: 0 <= k < L.nr(). of paired numbers: (L(k,i), R(k,i)) for k: 0 <= k < L.nr().
Therefore, COR(i) is a value between -1 and 1 inclusive where 1 Therefore, COR(i) is a value between -1 and 1 inclusive where 1
indicates perfect correlation and -1 perfect anti-correlation. indicates perfect correlation and -1 perfect anti-correlation. Note
that this function assumes the input data vectors have been centered
(i.e. made to have zero mean). If this is not the case then it will
report inaccurate results.
