## Maximum-entropy from the probability calculus: exchangeability, sufficiency

ArXiv (0)

Maximum-entropy distributions are shown to appear in the probability calculus as approximations of a model by exchangeability or a model by sufficiency, the former model being preferable. The implications of this fact are discussed, together with other questions: Prediction or retrodiction? How good is the maximum-entropy approximation? Is this a "derivation" of maximum-entropy?
