WebAug 8, 2024 · A lot is known about the Gaussian distribution, and as such, there are whole sub-fields of statistics and statistical methods that can be used with Gaussian data. In this tutorial, you will discover the Gaussian distribution, how to identify it, and how to calculate key summary statistics of data drawn from this distribution. WebClosed 10 months ago. Is there a more-or-less standard statistical test out there for checking whether a multivariate data set is being drawn from a multivariate Gaussian distribution? I suppose I could calculate the empirical mean vector and covariance matrix and then use them to calculate the likelihood, but is there a better way? Many thanks!
