Dirichlet distribution - Wikipedia
WebThe Dirichlet distribution also satis es the expansion or combination rule, which allows us to increase the dimensionality of a Dirichlet distribution. Note that the Dirichlet distribution over the 1-dimensional simplex is simply the Beta distribution. Let (ˇ 1; ;ˇ K) ˘Dirichlet( 1; ; K) and ˘Beta( 1b; 1(1 b)) for 0 <1. Then one dimension ... WebThe so-called Dirichlet distribution is the con-jugate family of priors for the multinomial dis-tribution. The Dirichlet distribution is such that π(θ;α) = ¡(Pk i=1 αi) Qk i=1 ¡(αi) Yk i=1 θαi−1 i I£(θ), where αi > 0, i = 1,...,k. Using this prior in the multinomial experiment yields a Dirichlet posterior with parameters yi+ αi ...
