Inserts a student_t_distribution random number distribution __x into the output stream __os.
bool operator== (const student_t_distribution &__d1, const student_t_distribution &__d2)
Return true if two Student t distributions have the same parameters and the sequences that would be generated are equal.

Extracts a student_t_distribution random number distribution __x from the input stream __is.

Detailed Description

  template<typename _RealType = double>
class std::student_t_distribution< _RealType >" A student_t_distribution random number distribution. The formula for the normal probability mass function is: p(x|n) = ac{1}{qrt(ni)} ac{Gamma((n+1)/2)}{Gamma(n/2)} (1 + ac{x^2}{n}) ^{-(n+1)/2} ]
