| Summary : Multinormal Mixture distribution
|
Description :
This module allows to calculate the density of a mixture of n multivariate
normal simetric distributions.
Given a multivariate normal simetric distributions in IR**k (IR := the real
numbers domain) such that its density function can be calculated as...
p($x) = (sqrt(2*pi)*$sigma)**(-$k) * exp(|$x-$mu|/$sigma)**2)
where
$x is a vector of dimension k,
$mu is the median vector of the distribution,
$d = |$x - $mu|, the distance between the median and x
$sigma is the standard deviation,
(the covariance matrix is restricted to $sigma*$Ik being $Ik
the identity matrix of size k)
A multivariate normal distribution mixin is defined as a weighted mix of a
set of multivariate normal simetric distributions, such that its density
function is...
pm(x) = sum ( $alpha[$i] * p[$i](x) )
