The Gaussian distribution
www.cse.wustl.eduThe Gaussian distribution has a number of convenient analytic properties, some of which we describe below. Marginalization Often we will have a set of variables x with a joint multivariate Gaussian distribution, but only be interested in reasoning about a subset of these variables. Suppose x has a multivariate Gaussian distribution: p(x j ...
Conjugate Bayesian analysis of the Gaussian distribution
www.cs.ubc.caThe 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. The use of conjugate priors allows all the results to be derived in closed form. Unfortunately, different books use different conventions on how to parameterize the various
