| Abstract: | A possibility function for a variable A over a set X is defined as a mapping from subsets of X to the unit interval, indicating the possibility that a realization of A is in that subset of X. We discuss the types of possibility functions derived from various types of informational structure about A. We discuss ordinal, fuzzy, and cardinal information. |
