Detailed Description

template<typename _RealType = double>
class std::fisher_f_distribution< _RealType >

A fisher_f_distribution random number distribution.

The formula for the normal probability mass function is

\[ p(x|m,n) = \frac{\Gamma((m+n)/2)}{\Gamma(m/2)\Gamma(n/2)} (\frac{m}{n})^{m/2} x^{(m/2)-1} (1 + \frac{mx}{n})^{-(m+n)/2} \]
