std::negative_binomial_distribution<IntType>::negative_binomial_distribution – std::negative_binomial_distribution<IntType>::negative_binomial_distribution

Synopsis

negative_binomial_distribution()
    : negative_binomial_distribution(1){}(1)(since C++ 11)

          explicit negative_binomial_distribution(IntType k, double p = 0.5);
(2)(since C++ 11)

    explicit negative_binomial_distribution(const param_type &params);
(3)(since C++ 11)

Constructs a new distribution object. (2) uses k and p as the distribution parameters. (3) uses params as the distribution parameters.

Parameters

k – the k distribution parameter (number of trial successes)
p – the p distribution parameter (probability of a trial generating true)
params – the distribution parameter set

Notes

Requires that 0 < p ≤ 1 and 0 < k.
If p == 1, subsequent calls to the operator() overload that does not accept a param_type object will cause undefined behavior.
The default-constructed std::negative_binomial_distribution is equivalent to the default-constructed std::geometric_distribution.
