WebOct 25, 2024 · 1.1 Background. The famous de Finetti theorem in classical probability theory clarifies the relationship between permutation symmetry and the independence of a sequence of random variables [dF31, dF37, EL55].Consequently an infinite sequence of symmetric random variables can be written as a convex combination of an independent …
WebOct 24, 2024 · 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 sequence of Bernoulli random … WebTheorem 8.4 is often called a finite style de Finetti theorem because n and k are both fixed and finite. This result can be used to provide an easy proof of the infinite de Finetti theorem.
