Detailed Description

  template<typename _IntType = int>
class std::negative_binomial_distribution< _IntType >" A negative_binomial_distribution random number distribution. The formula for the negative binomial probability mass function is $p(i) = n} p^i (1 - p)^{t - i}$ where $t$ and $p$ are the parameters of the distribution.
