FISHER function

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.



X     is a numeric value for which you want the transformation.


  • 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:




Description (Result)
