cs229.stanford.eduA 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 ...

Murphy∗ murphyk@cs.ubc.ca Last updated October 3, 2007 1 Introduction The Gaussian or normal distribution is one of the most widely used in statistics. Estimating its parameters using Bayesian inference and conjugate priors is also widely used.
