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) =
ac{Gamma((m+n)/2)}{Gamma(m/2)Gamma(n/2)} (ac{m}{n})^{m/2} x^{(m/2)-1}
(1 + ac{mx}{n})^{-(m+n)/2} ]
