"WebFisher developed a transformation now called "Fisher's z-transformation" that converts Pearson's r to the normally distributed variable z. The formula for the transformation is: z_r = tanh^{-1}(r) = \frac{1}{2}log\left ( \frac{1+r}{1-r}\right ) Value. z value corresponding to r (in FisherZ) r corresponding to z (in FisherZInv) " - Fisher z-transformation
