matrix gamma distribution

In probability theory and statistics, the chi-squared distribution with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables. scale parameter, | The compound distribution resulting from compounding a matrix normal with a matrix gamma prior over the precision matrix is a generalized matrix t-distribution. In statistics, the matrix t-distribution is the generalization of the multivariate t-distribution from vectors to matrices. It is a more general version of the Wishart distribution, and is used similarly, e.g. It is the conjugate prior of a multivariate normal distribution with unknown mean and covariance matrix. At best, it is an alternate parameterization of the Wishart and should … The complex normal family has three parameters: location parameter μ, covariance matrix , and the relation matrix . r β 2 The multivariate normal distribution is often used to describe, at least approximately, any set of (possibly) correlated real-valued random variables each of which clusters around a mean value. 2 It is a multivariate generalization of the beta distribution, hence its alternative name of multivariate beta distribution (MBD). In probability and statistics, the Dirichlet distribution, often denoted , is a family of continuous multivariate probability distributions parameterized by a vector of positive reals.
