Hewitt-Savage 0 − 1 Law 6. De-Finetti’s Theorem Martingale Convergence Theorem Theorem 1. (Doob) Suppose X n is a super-martingale which A famous theorem of De Finetti (1931) shows that an exchangeable sequence of $\{0, 1\}$-valued random variables is a unique mixture of coin tossing processes. Many generalizations of this result have been found; Hewitt and Savage (1955) for example extended De Finetti's theorem to arbitrary compact state spaces (instead of just $\{0, 1\}$).

Versions of de Finetti's theorem for finitely exchangeable sequences [1] and for exchangeable Markov Chains [2] have been proved by Diaconis and Freedman. [3] Two notions of partial exchangeability of arrays, known as separate and joint exchangeability lead to extensions of de Finetti's theorem for arrays by Aldous and Hoover. [4] O conceito de permutabilidade (exchangeability) foi introduzido por de Finetti. O teorema de De Finetti explica a relação matemática entre a independência e permutabilidade. Uma sequência infinita ,,, … de variáveis aleatórias é dita ser permutável se para qualquer número cardinal finito n e qualquer duas sequências finitas i 1 3.

2019-12-05 · A nonstandard proof of de Finetti's theorem. We give a nonstandard analytic proof of de Finetti's theorem for an exchangeable sequence of Bernoulli random variables. The theorem postulates that such a sequence is uniquely representable as a mixture of iid sequences of Bernoulli random variables. de Finetti’s complete bibliography can be found in Daboni (1987). Many recent developments of de Finetti’s work are mentioned here and brie y described, as are the lengthier developments, in note within the text. 1. HISTORICAL NOTES 1.1 Essential Biography De Finetti was born of Italian parents on 13 June 1906 in Innsbruck (Austria).

2019-10-25 Our proof of Theorem 2.4 is based on the manifest affinity of (3.2) as a function of Γ N , and the quantum de Finetti theorem, a generalization of the classical de Finetti-Hewitt-Savage theorem DE FINETTI WAS RIGHT: PROBABILITY DOES NOT EXIST ABSTRACT. De Finetti’s treatise on the theory of probability begins with the provocative statement PROBABILITY DOES NOT EXIST, meaning that prob-ability does not exist in an objective sense. Rather, probability … De Finetti's theorem suggests a mixture of IID models might be near the orbit. Based on the experience of Joe and Mary we make one final supposition.
