_Traits > std::basic_ostream< _CharT, _Traits > &
operator<< (std::basic_ostream< _CharT, _Traits >
&__os, const std::student_t_distribution< _RealType1 >
&__x)
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. template<typename _RealType1

_CharT, _Traits > & operator>>
(std::basic_istream< _CharT, _Traits > &__is,
std::student_t_distribution< _RealType1 > &__x)
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}{rt(ni)}
ac{Gamma((n+1)/2)}{Gamma(n/2)} (1 + ac{x^2}{n}) ^{-(n+1)/2} ]
