Calculates the Pearson correlation distance between elements of two ranges.

  If elements of both ranges are unweighted the distance is
  calculated as \form#307, where \form#62 and \form#63@_fakenl are the two points and C is the %Pearson correlation.

  If elements of one or both of ranges have weights the distance
  is calculated as \form#308@_fakenl,
  where and \form#280 and \form#68 are weights for the
  elements of the first and the second range, respectively, and

$m_x=\sum w_{x,i}w_{y,i}x_i/\sum w_{x,i}w_{y,i}$ and correspondingly for $ m_y $ . If the elements of one of the two ranges are unweighted, the weights for these elements are set to unity.
