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 $p(i) = {} p^i (1 - p)^{t - i}$ where
       $t$ and $p$ are the parameters of the distribution.                        n
                                                                                  }
