Returns the Fisher transformation at x. This transformation produces a function that is approximately 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:
