WebBy the Portmanteau theorem, it is su cient to show that Eg(B n) ! Eg(B) for every bounded continuous g : C[0;1] !R. For the rest of the proof, see Durrett or Kallenberg. 1.2 Applications of Donsker’s theorem We can get nice statements about Brownian motion by treating it as the limit of random walks. Example 1.1.

WebDonsker's theorem identifies a certain stochastic process as a limit of empirical processes. It is sometimes called the functional central limit theorem. A centered and scaled version of empirical distribution function Fn defines an empirical process G n ( x) = n ( F n ( x) − F ( x)) indexed by x ∈ R.

In probability theory, Donsker's theorem (also known as Donsker's invariance principle, or the functional central limit theorem), named after Monroe D. Donsker, is a functional extension of the central limit theorem.
