WebDec 25, 2024 · Suppose we have a Martingale that produces IID observations at constant intervals out of a distribution with finite variance, let's say once every moment t. If we collect observations of the Martingale on long enough intervals, eg. every 30t, following the Martingale CLT (and Classical CLT), our observations have the limit of Brownian motion. WebApr 20, 2024 · It may be emphasized that Donsker’s FCLT and invariance principle are immediate offshoots of (b), whose proof here does not require the use of the central limit theorem, neither for the classical case for i.i.d. sequences nor for the martingale CLT derived above (Theorem 15.1). Indeed, the latter CLTs just follow as simple consequences!
Web4. The martingale approach to Markov chain central limit theorems Let {X n} be a Markov chain with transition p. Let h be a measurable function on the state space such that h(X k) is integrable for all k. The initial distribution is arbitrary at this point. Then there is a standard way to produce a martingale associated to h. Namely, by the ... WebApr 10, 2024 · Girsanov Example. Let such that . Define by. for and .
