Inserts a fisher_f_distribution random number distribution __x into the output stream __os. bool operator== (const fisher_f_distribution &__d1, const fisher_f_distribution &__d2)
Return true if two Fisher f distributions have the same parameters and the sequences that would be generated are equal. template<typename _RealType1 , typename _CharT , typename _Traits > std::basic_istream< _CharT, _Traits > & operator>> (std::basic_istream< _CharT, _Traits > &__is, std::fisher_f_distribution< _RealType1 > &__x)
Extracts a fisher_f_distribution random number distribution __x from the input stream __is.

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} ]
