A student_t_distribution random number distribution produces random numbers x distributed according to the probability density function
p(x|n)=1√nπ⋅Γ((n+1)/2)Γ(n/2)⋅(1+x2n)−(n+1)/2.
template<class RealType = double> class student_t_distribution { public: using result_type = RealType; using param_type = unspecified; explicit student_t_distribution(RealType n = 1); explicit student_t_distribution(const param_type& parm); void reset(); template<class URBG> result_type operator()(URBG& g); template<class URBG> result_type operator()(URBG& g, const param_type& parm); RealType n() const; param_type param() const; void param(const param_type& parm); result_type min() const; result_type max() const; };
explicit student_t_distribution(RealType n = 1);
Effects: Constructs a student_t_distribution object; n corresponds to the parameter of the distribution.
RealType n() const;
Returns: The value of the n parameter with which the object was constructed.
