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.

The symmetric states on a quasi local C*–algebra on the infinite set of indices J are those invariant under the action of the group of the permutations moving only a finite, but arbitrary, number of elements of J. The celebrated De Finetti Theorem describes the structure of the symmetric states (i.e. exchangeable probability measures) in classical probability.

In probability theory, de Finetti's theorem states that exchangeable observations are conditionally independent given some latent variable to which an epistemic probability distribution would then be assigned. It is named in honor of Bruno de Finetti.

Bruno de Finetti. Bruno de Finetti (13 June 1906 – 20 July 1985) was an Italian probabilist statistician and actuary, noted for the "operational subjective" conception of probability. De Finetti, Countable Additivity, Consistency and Coherence 5 often described as rationality constraints on probability functions which so impressed Kyburg makes any … 2016-02-18 In probability theory, de Finetti's theorem explains why exchangeable observations are conditionally independent given some latent variable to which an epistemic probability distribution would then be assigned.

One form that the connection takes in the Bayesian framework is to relate subjective beliefs about the unknown but –xed probability law on S(the unknown fiparameterfl), repre- In probability theory, de Finetti's theorem states that exchangeable observations are conditionally independent given some latent variable to which an epistemic probability distribution would then be assigned. It is named in honor of Bruno de Finetti. De Finetti’s theorem characterizes all {0, 1}-valued exchangeable sequences as a ‘mixture’ of sequences of independent random variables.

In tro duction. This Außerdem bewies er 1931 den Satz von de Finetti (auch Darstellungssatz von de Finetti, englisch: de Finetti's theorem oder de Finetti's representation theorem), der besagt, dass alle ins Unendliche fortsetzbaren Folgen einer vertauschbaren Zufallsvariablen als Wichtung einer identisch und unabhängig verteilten Zufallsvariablen dargestellt werden können – und umgekehrt. The celebrated De Finetti Theorem describes the structure of the symmetric states (i.e. exchangeable probability measures) in classical probability. In the present paper we extend the De Finetti Theorem to the case of the CAR algebra, that is for physical systems describing Fermions.
