WebLike a lot of theorems that are imprecisely stated, BvM is both almost always true and absolutely never true. So in order to do anything useful, we need to actually think about the assumptions. They are written, in great and loving detail, in Section 2.25 of these lecture notes from Richard Nickl. WebBvM is greatly inspired by the framework developed in [10] for functionals in nonparametrics. However, the theory in this paper is di erent from theirs since we can …

WebAbstract We study the Bernstein-von Mises (BvM) phenomenon, i.e., Bayesian credible sets and frequentist confidence regions for the estimation error coincide asymptotically, for the infinite-dimensional Gaussian white noise model governed by Gaussian prior with diagonal-covariance structure. WebTheorem 1 below gives the Bayesian analysis; Theorem 2, the frequentist. Theorems 3 and 4 draw the implications. There is an 12 consistency result in Theorem 5. Section 2 has some complements and details. Section 3 makes the connection with stochastic processes. We focus on one infinite-dimensional functional, the square of the 12 norm.
