Polya tree process

碩士 === 國立交通大學 === 統計學研究所 === 101 === Polya tree process is a large class of prior distributions, which Dirichlet process is included as a special case of Polya trees process. Like Dirichlet prior, the Polya tree prior also able to form a conjugate class for the posterior distributions. However, Poly...
