Measure-valued stochastic processes

Moving masses



Measure-valued random variates with some kind of dependence with respect to an index.

Dependent Dirichlet process

Invented by Steven N. MacEachern (1999), this idea produced a whole family of related models, reviewed exhaustingly in Quintana et al. (2022) and Foti and Williamson (2015). The idea is to construct correlation amongst the defining RVs of a Dirichlet process in the stick-breaking construction by declaring them to be given as some transform a stochastic process. Posterior inference for these models does not appear to be especially nice; I would like a nice reference for that.

Discrete case
