Hjort , Walker : Quantile pyramids for Bayesian nonparametrics

Nils Lid Hjort and Stephen G. With quantile pyramids we instead fix probabilities and use random partitions.

For nonparametric Bayesian inference we use a prior which supports piecewise linear quantile functions, based nonpaametrics the need to work with a finite set of partitions, yet we show that the limiting version of the prior exists. We also discuss and investigate an alternative model based on the so-called substitute likelihood.

Both approaches factorize in a convenient way leading to relatively straightforward analysis via MCMC, since analytic summaries of posterior distributions are too complicated. We give conditions securing the existence of an absolute continuous quantile process, and discuss consistency and approximate normality for the sequence of posterior distributions.
