Credal sets

The convex set of distributions maintained by an agent is called the agent's credal set, and its existence is postulated on the grounds of axioms about preferences [14].2 To simplify terminology, the term credal set is used only when it refers to a set of distributions containing more than one element. A closed convex set of joint distributions is called a joint credal set.

This paper deals with credal sets that are defined as the convex hull of a finite number of probability distributions; such finitely generated credal sets are polytopes in the space of probability distributions.
