chi_squared_distribution Class

Generates a chi-squared distribution.

template<class RealType = double>
    class chi_squared_distribution {
public:
    typedef RealType result_type;
    struct param_type;
    explicit chi_squared_distribution(RealType n0 = 1);
    explicit chi_squared_distribution(const param_type& par0);
    RealType n() const;
    param_type param() const;
    void param(const param_type& par0);
    result_type min() const;
    result_type max() const;
    void reset();
    template<class Engine>
        result_type operator()(Engine& eng);
    template<class Engine>
        result_type operator()(Engine& eng,
            const param_type& par0);
private:
    RealType stored_n;
    };

Parameters

Parameter	Description
RealType	The floating-point result type.

Remarks
