In probability theory, de Finetti's theorem states that exchangeable observations are conditionally independent relative to some latent variable. An epistemic probability distribution could then be assigned to this variable. It is named in honor of Bruno de Finetti. For the special case of an exchangeable … See more A Bayesian statistician often seeks the conditional probability distribution of a random quantity given the data. The concept of exchangeability was introduced by de Finetti. De Finetti's theorem explains a mathematical … See more Here is a concrete example.

According to de Finetti such a (possibly very vague) degree-of-belief can be quantified through thought experiments involving urns with a varying fraction of differently colored balls. A degree-of-belief value … if a b 1 then a+b a2+b2

WebDe Finetti’s reaction to Smith’s paper was essentially negative and, as he explained, led to the addition of two short sections in the final version of [16]. We discuss de Finetti’s reactions below. As for Williams’ paper, de Finetti read it in a later phase of his activity, the mid-seventies, and we are aware of no written comments on it. WebMar 26, 2024 · 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.
