FISHER

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 ³ 1, FISHER returns the #NUM! error value.

The equation for the Fisher transformation is:

Example

FISHER(0.75) equals 0.972955
