The Multivariate Gaussian Distribution
1 Relationship to univariate Gaussians Recall that the density function of a univariate normal (or Gaussian) distribution is given by p(x;µ,σ2) = 1 √ 2πσ exp − 1 2σ2 (x−µ)2 . Here, the argument of the exponential function, − 1 2σ2(x−µ) 2, is a quadratic function of the variable x.
