Returns the Fisher transformation at x. This transformation produces a function that is normally distributed rather than skewed. Use this function to perform hypothesis testing on the correlation coefficient.
Syntax
FISHER(x)
X is a numeric value for which you want the transformation.
Remarks
 If x is nonnumeric, FISHER returns the #VALUE! error value.
 If x ≤ 1 or if x ≥ 1, FISHER returns the #NUM! error value.
 The equation for the Fisher transformation is:
