std::tr1::geometric_distribution(3)
NAME
std::tr1::geometric_distribution
SYNOPSIS
Detailed Description
- template<typename _IntType = int, typename _RealType = double> class
- std::tr1::geometric_distribution< _IntType, _RealType > The formula for the geometric probability mass function is $ p(i) = (1 - p)p^{i-1} $ where $ p $ is the parameter of the distribution.
