DEFINETTIAN CONSENSUS

摘要

It is always possible to construct a real function φ, given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that φ(X) and φ(Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the 'opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO).
