Description

Fisher r to z transformation. FISHERR2Z(r) calculates the Fisher z-transformed value of r. The argument r must be greater than -1 and less than 1.

z is calculated as follows:

FisherR2Z function$$z = {1 \over 2} \ln \left({1+r \over 1-r}\right) $$

Example

FISHERR2Z(0.8) equals 1.09861229
