## Fisher Inv

 doublefisher_inv( double x )[inline]
The inverse of the Fisher transformation is defined by: where x is the number you want to apply the inverse of the Fisher transformation on.

The inverse of the Fisher Transformation is the inverse of the FISHER() function. Use this transformation when analyzing correlations between ranges or arrays of data. If y = FISHER(x), then FISHERINV(y) = x.

### Example 1

#include <codecogs/statistics/moments/fisher_inverse.h>
#include <iostream>
int main()
{
double inv= Stats::Moments::fisher_inv(0.8);
std::cout << "The inverse of the Fisher transformation is: " << inv << std::endl;
return 0;
}
Output:
The inverse of the Fisher transformation is:0.664037

### Parameters

 x a numeric value for which you want the transformation

### Returns

the inverse of the Stats/Moments/Fisher transformation.
