`r` formula -
  1. Auto Select method
  2. Method-1 : `r = (n * sum xy - sum x * sum y)/(sqrt(n * sum x^2 - (sum x)^2) * sqrt(n * sum y^2 - (sum y)^2))`
  3. Method-2 : `r = (sum (x-bar x)(y-bar y))/(sqrt(sum (x-bar x)^2) * sqrt(sum (y-bar y)^2))`
    Or `r = (n * sum dxdy - sum dx * sum dy)/( sqrt(n * sum dx^2 - (sum dx)^2) * sqrt(n * sum dy^2 - (sum dy)^2))`
