FISHERINV(Number)

is the value to find inverse of fisher transformation.
- FISHERINV(), returns the inverse of the Fisher transformation.

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  $Number$  value is non-numeric.

The syntax is to calculate FISHERINV in ZOS is .
- $Number$ is the value to find inverse of fisher transformation.
For e.g.,FISHERINV(0.4521..0.507..0.01)
