The Multivariate Gaussian Distribution - Stanford University

SpletIn the case where you only assume that $\mathbf{X}$ and $\mathbf{Y}$ are marginally Gaussian, you can't say much about the joint density of $(\mathbf{X},\mathbf{Y})$, and you certainly can't conclude that the joint density is a Gaussian density. In the answer below I've added the additional assumption that the joint distribution is indeed Gaussian. SpletGaussian noise, named after Carl Friedrich Gauss, is statistical noise having a probability density function (PDF) equal to that of the normal distribution, which is also known as the Gaussian distribution. In other words, the values that the noise can take on are Gaussian-distributed. its standard deviation.
