De Finetti's Representation Theorem gives in a single take, within the subjectivistic interpretation of probabilities, the raison d'être of statistical models and the meaning of parameters and their prior distributions. Suppose that the random variables X 1, …, X n represent the results of successive tosses of a coin, with values 1 and 0

Our general de Finetti theorems work for non-easy quantum groups, which generalizes a recent work of Banica, Curran and Spe-icher. For in nite sequences, we determine maximal distributional symmetries which means the corresponding de Finetti theorem fails if the sequence satis es more symmetries other than the maximal one.

We present a new, elementary proof of de Finetti’s Theorem. The purpose of this paper is to make this theorem accessible to a broader community through an essentially self-contained proof. 3 relations: Bruno de Finetti, De Finetti diagram, De Finetti's theorem. Bruno de Finetti.

We include this in a course on statistical inference, because the theorem is a cornerstone of of Bayesian statistical inference, and is a critique of objectivistic modes of statistical inference.

For the special case of an exchangeable sequence of Bernoulli random variables it states that such a sequence is a "mixture" of sequences of independent and identically distributed Bernoulli random variables. A De Finetti's theorem asserts, moreover, that this convex set is a simplex, i.e. any of its points is the barycentre of a unique probability measure, called the mixing measure, concentrated on the extremal points. This statement remains true for probability measures that are invariant under groups much more general than the (finite) permutations on the natural integers, while the product structure of the extremals seems to be specific to the permutation group. de Finetti, theorem is, as such, a result in probability theory.
