FISHERINV(y)

This function gives the inverse of the Fisher transformation.
We use this to test the correlations between set of data.
The Inverse of the Fisher transformation is: $x={\frac {e^{2y-1}}{e^{2y+1}}}$ i.e $y=FISHER(x)$ , then $FISHERINV(y)=x$
It can be used to construct a confidence interval.
A confidence interval (CI) is a type of interval estimate of a population parameter and is used to indicate the reliability of an estimate.

This function will give the result as error when the  $y$  value is non-numeric.
