Definition of the Fisher transformation:


Here Z is approximately normally distributed with mean x.

int main()
{
double fis = Stats::Moments::fisher(0.57);
std::cout << "The Fisher transformation is: " << fis << std::endl;
return 0;
}
Output:
The Fisher transformation is: 0.647523

Parameters

 x a numeric value for which you want the transformation

Returns

the Fisher transformation of x
