We propose a probability model for a family of unknown distributions
indexed with covariates. The marginal model for each distribution is
a Polya tree prior. The proposed model introduces the desired
dependence across the marginal Polya tree models by defining dependent
random branching probabilities of the unknown distributions. The
dependence is on the corresponding...
