template<class IntType = int>
    class negative_binomial_distribution {
public:
    typedef IntType result_type;
    struct param_type;
    explicit negative_binomial_distribution(result_type k0 = 1,
        double p0 = 0.5);
    explicit negative_binomial_distribution(const param_type& par0);
    result_type k() const;
    double p() 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:
    result_type stored_k;
