A method to construct exponential families by representation theory
arXiv:1811.01394
Abstract
In this paper, we give a method to construct "good" exponential families systematically by representation theory. More precisely, we consider a homogeneous space as a sample space and construct an exponential family invariant under the transformation group by using a representation of . The method generates widely used exponential families such as normal, gamma, Bernoulli, categorical, Wishart, von Mises, Fisher-Bingham and hyperboloid distributions.
