WebDoob-Meyer decomposition, which allows to better account for the bias and provides a new tool for SR analysis of non-linear errors. We then prove that using pairwise summation in variance computations gives bounds in p log(n) in Section 6. We nally compare the obtained bounds by algorithm WebJan 1, 2004 · W e follow the book of K AR ATZA S and S HR EV E [2]; in the proof o f the Doob-Meyer decomposition theorem, part of the argument is taken from the bo ok of K …

(PDF) A short Proof of the Doob-Meyer Theorem
In the theory of stochastic processes in discrete time, a part of the mathematical theory of probability, the Doob decomposition theorem gives a unique decomposition of every adapted and integrable stochastic process as the sum of a martingale and a predictable process (or "drift") starting at … See more Existence Using conditional expectations, define the processes A and M, for every n ∈ I, explicitly by and See more The Doob decomposition theorem can be generalized from probability spaces to σ-finite measure spaces.
