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

NAME

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.
