FISHER (Number)

is the value to find the Fisher transformation.
- FISHER(), returns the Fisher transformation.

This function gives the value of Fisher Transformation for the given number.
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 $FISHER(Number)$ , $Number$ is the value 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. $Number$  is non-numeric
2. $Number\leq -1$  or  $Number\geq 1$ .

The syntax is to calculate FISHER in ZOS is .
- $Number$ is the value to find the Fisher transformation.
For e.g.,FISHER(0.1..0.4..0.1)
