Combination of Upper and Lower Probabilities
نویسندگان
چکیده
In this paper, we consider several types of in formation and methods of combination asso ciated with incomplete probabilistic systems. \Ve discriminate between 'a priori' and evi dential information. The former one is a de scription of the whole population, the latest is a restriction based on observations for a particular case. Then, we proposse different combination methods for each one of them. 'We also consider conditioning as the hetero geneous combination of 'a priori' and eviden tial information. The evidential information is represented as a convex set of likelihood func tions. These will have an associated possi bility distribution with behavior according to classical Possibility Theory.

Abstract Dempster Shafer theory is the most important method of reviewing uncertainty for information system. This theory as introduced by Dempster using the concept of upper and lower probabilities extended later by Shafer. Another important application of entropy as a basic concept in the information theory can be used as a uncertainty measurement of the system in specific situation In th...
متن کاملExact maximum coverage probabilities of confidence intervals with increasing bounds for Poisson distribution mean
A Poisson distribution is well used as a standard model for analyzing count data. So the Poisson distribution parameter estimation is widely applied in practice. Providing accurate confidence intervals for the discrete distribution parameters is very difficult. So far, many asymptotic confidence intervals for the mean of Poisson distribution is provided. It is known that the coverag...
متن کاملPropagation of 2-Monotone Lower Probabilities on an Undirected Graph
Lower and upper probabilities, also known as Choquet capacities, are widely used as a con venient representation for sets of probability distributions. This paper presents a graphi cal decomposition and exact propagation al gorithm for computing marginal posteriors of 2-monotone lower probabilities (equivalently, 2-alternating upper probabilities).
متن کاملSymmetric Upper Probabilities
As a first step toward developing statistical models based on upper and lower probabilities, we study upper probabilities and upper expectations on the unit interval that are symmetric, by which we mean invariant with respect to equimeasurability. These upper probabilities are generalizations of uniform probability measures. We give some characterizations of these upper probabilities. Specifica...
متن کاملData Fusion in the Transferable Belief Model
When Shafer introduced his theory of evidence based on the use of belief functions, he proposed a rule to combine belief functions induced by distinct pieces of evidence. Since then, theoretical justifications of this socalled Dempster’s rule of combination have been produced and the meaning of distinctness has been assessed. We will present practical applications where the fusion of uncertain ...
متن کاملNew Distributions for Modeling Subjective Lower and Upper Probabilities
This paper presents an investigation of approaches to modeling lower and upper subjective probabilities. A relatively unexplored approach is introduced, based on the fact that every cumulative distribution function (CDF) with support (0,1) has a “dual” CDF that obeys the conjugacy relation between coherent lower and upper probabilities. A new 2-parameter family of “CDF-Quantile” distributions w...
