FISHER(x)

This function gives the value of Fisher Transformation at $x$ .
Fisher Transformation is used to test the hypothesis of two correlations.
It is mainly associated with the Pearson Product-Moment Correlation coefficient for bi-variate normal observations.
In $FISHER(X)$ , $x$ is the number which ranges between -1 to +1.
The transformation is defined by : $z={\frac {1}{2}}ln(1+{\frac {x}{1-x}})=arctanh(x)$

where $ln$ is the natural logarithm function and $arctanh$ is the Inverse Hyperbolic function.

1. $x$  is non-numeric
2. $x\leq -1$  or  $x\geq 1$ .
