NAME
std::poisson_distribution< _IntType > - A discrete Poisson random number distribution.
SYNOPSIS
Classes struct param_type Public Types typedef _IntType result_type Public Member Functions poisson_distribution (const param_type &__p) poisson_distribution (double __mean=1.0) template<typename _ForwardIterator , typename _UniformRandomNumberGenerator > void __generate (_ForwardIterator __f, _ForwardIterator __t, _UniformRandomNumberGenerator &__urng) template<typename _ForwardIterator , typename _UniformRandomNumberGenerator > void __generate (_ForwardIterator __f, _ForwardIterator __t, _UniformRandomNumberGenerator &__urng, const param_type &__p) template<typename _UniformRandomNumberGenerator > void __generate (result_type *__f, result_type *__t, _UniformRandomNumberGenerator &__urng, const param_type &__p) result_type max () const Returns the least upper bound value of the distribution. double mean () const Returns the distribution parameter mean. result_type min () const Returns the greatest lower bound value of the distribution. template<typename _UniformRandomNumberGenerator > result_type operator() (_UniformRandomNumberGenerator &__urng) Generating functions. template<typename _UniformRandomNumberGenerator > result_type operator() (_UniformRandomNumberGenerator &__urng, const param_type &__p) param_type param () const Returns the parameter set of the distribution. void param (const param_type &__param) Sets the parameter set of the distribution. void reset () Resets the distribution state. Friends template<typename _IntType1 , typename _CharT , typename _Traits > std::basic_ostream< _CharT, _Traits > & operator<< (std::basic_ostream< _CharT, _Traits > &__os, const std::poisson_distribution< _IntType1 > &__x) Inserts a poisson_distribution random number distribution __x into the output stream __os. bool operator== (const poisson_distribution &__d1, const poisson_distribution &__d2) Return true if two Poisson distributions have the same parameters and the sequences that would be generated are equal. template<typename _IntType1 , typename _CharT , typename _Traits > std::basic_istream< _CharT, _Traits > & operator>> (std::basic_istream< _CharT, _Traits > &__is, std::poisson_distribution< _IntType1 > &__x) Extracts a poisson_distribution random number distribution __x from the input stream __is.
Detailed Description
template<typename _IntType = int> class std::poisson_distribution< _IntType >" A discrete Poisson random number distribution. The formula for the Poisson probability density function is $p(i|) = ac{^i}{i!} e^{-}$ where $$ is the parameter of the distribution. Definition at line 4330 of file random.h.
