Web3. FISHER TRANSFORMATION Fisher developed a transformation of r that tends to become normal quickly as N increases. It is called the r to z transformation. We use it to conduct tests of the correlation coefficient and calculate the confidence interval. For the transformed z, the approximate variance V(z) = 1/(n-3) is independent of the correlation.
