Fisher Z Transformation For Correlation Coefficients

fisher s transformation of the correlation coefficient the do.

20 09 2017 this transformation is sometimes called fisher s z transformation because the letter z is used to represent the transformed correlation z arctanh r how he came up with that transformation is a mystery to me but he was able to show that arctanh is a normalizing and variance stabilizing transformation.
