We construct a prequential test of probabilistic forecasts that does not reject correct forecasts when the data-generating processes is exchangeable and is not manipulable by a false forecaster.

Restricting exchangeable nonparametric distributions

Distributions over exchangeable matrices with infinitely many columns, such as the Indian buffet process, are useful in constructing nonparametric latent variable models. However, the distribution imp...

The aim of this article is to fill this void.We present three abstract normal approximation theorems using exchangeable pairs in multivariate contexts,one for situations in which the underlying symmet...

This is a survery paper on Poisson approximation using Stein's method of exchangeable pairs. We illustrate using Poisson-binomial trials and many variations on three classical problems of combinatoria...

In this survey we recall the basic results of the theory of exchangeable laws, and then explain the probabilistic versions of various interesting questions from graph and hypergraph theory that their ...

We introduce and study a class of exchangeable random graph ensembles. They can
be used as statistical null models for empirical networks, and as a tool for theoretical
investigations. We provide ge...
