WorksheetFunction.Fisher (Excel)

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.

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

Fisher (Arg1)

Arg1: x - a numeric value for which you want the transformation.
