More on Multivariate Gaussians

A vector-valued random variable x ∈ Rn is said to have a multivariate normal (or Gaus-sian) distribution with mean µ ∈ Rnn ++ 1 if its probability density function is given by p(x;µ,Σ) = 1 (2π)n/2|Σ|1/2 exp − 1 2 (x−µ)TΣ−1(x−µ) . 2 Gaussian facts Multivariate Gaussians turn out to be extremely handy in practice due to the ...

The Gaussian distribution

We may extend the univariate Gaussian distribution to a distribution over d-dimensional vectors, producing a multivariate analog. The probablity density function of the multivariate Gaussian distribution is p(x j ; ) = N(x; ; ) = 1 Z exp 1 2 (x )> 1(x ) : The normalization constant Zis Z= p det(2ˇ 1) = (2ˇ)d=2(det ) =2: 1
