Detailed Description

template<class Distribution>
class kjb::Mixture_distribution< Distribution >

This class implements a mixture distribution. In other words, it is the sum of a finite number of fractions of distributions of the same type (with different parameters).

Template Parameters
DistributionThe type of distribution that makes up the different parts of the mixture

Constructor & Destructor Documentation

template<class Distribution>
kjb::Mixture_distribution< Distribution >::Mixture_distribution ( const std::vector< Distribution > &  distributions,
const std::vector< double > &  coefficients 
)
inline

Constructs a mixture distribution from the given distributions and mixing coefficients.

This constructore creates a mixture distribution with the given distributions and the given coefficients, where distributions[i] has mixing coefficient coefficients[i].

template<class Distribution>
kjb::Mixture_distribution< Distribution >::Mixture_distribution ( const std::vector< Distribution > &  distributions)
inline

Constructs a mixture distribution with equal mixing coefficients.

This constructore creates a mixture distribution with the given distributions and equal mixing coefficients. That is, distributions[i] has mixing coefficient 1 / distributions.size(), for all i.

template<class Distribution>
kjb::Mixture_distribution< Distribution >::Mixture_distribution ( const Distribution &  dist1,
const Distribution &  dist2,
double  pi1 
)
inline

Constructs two-element mixture distribution.

This constructore creates a mixture distribution with two elements, with the coefficient of the first one being pi1, and the coefficient of the second one being 1 - pi1.
