WebLecture 24: Dirichlet distribution and Dirichlet Process 5 where π1 ∼ Beta(1,α0), X is k−vector that takes on the value ej with probability G0(Ak), and V is independent of X and π1. We show that the k−dimensional Dirichlet distribution V ∼ Dir(G0(A1),...,G0(Ak)) satises Equation (1) and therefore, by fact 3, V is the unique distribution to satisfy this.

"Webnormal distribution with zero mean and unit standard de-viation. The idea behind one-dimensional LHS is easy to be understood. As shown in Fig. 3(a), LHS divides a given cumulative distribution function into M identical intervals and randomly chooses one value from each cumulative distribution interval to obtain M samples.
