Sampling theorem proof

WebIn probability theory, the optional stopping theorem(or sometimes Doob's optional sampling theorem, for American probabilist Joseph Doob) says that, under certain conditions, the expected valueof a martingaleat a stopping timeis equal to its initial expected value. WebDec 20, 2009 · The proof of Theorem 3 constructed simple stopping times such that . Then, As is a simple stopping time, is measurable and, is -measurable. So, is adapted. The remainder of the proof is identical to that given above for Theorem 2, except that we apply Theorem 3 instead of 1. Print Tweet Email Loading... Tagged Martingale math.PR …

WebStarting with the definition of the sample mean, we have: V a r ( X ¯) = V a r ( X 1 + X 2 + ⋯ + X n n) Rewriting the term on the right so that it is clear that we have a linear combination of X i 's, we get: V a r ( X ¯) = V a r ( 1 n X 1 + 1 n X 2 + ⋯ + 1 n X n) Then, applying the theorem on the last page, we get: WebOptional Stopping Theorem The OST says that ifat leastone of those conditions holds, then E[Z T] = E[Z 0] where T is a stopping time. This is equivalently to say that no matter how complex is our stopping strategy, if it isreasonable enough, then in expectation Z T have the same value than Z 0 Lecture 8: The Optional Stopping Theorem 13
