WebThis function implements biweight midcorrelation calculation (see references). If y is not supplied, midcorrelation of columns of x will be calculated; otherwise, the midcorrelation between columns of x and y will be calculated. Thus, bicor (x) is equivalent to bicor (x,x) but is more efficient.
