Introduction The Dirichlet distribution is conjugate to the multinomial distribution in the following sense. If random variables p= (p1,...,pk) satisfy Pk i=1pi = 1 and are Dirichlet, that is, they have a prior distribution … Web15 de set. de 2024 · Furthermore, as I showed in my answer, a scaled Dirichlet distribution only works when the dimension is 3. It is also tricky because a question with so little specifications is troubling and not a good standard. $\endgroup$ – Sextus Empiricus. Sep 15, 2024 at 16:48. 3
