NAME¶

std::negative_binomial_distribution::negative_binomial_distribution - std::negative_binomial_distribution::negative_binomial_distribution

Synopsis¶

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