چکیده

We provide some objective foundations for a belief revision process in a situation where (i) the decision-maker's initial probabilistic knowledge is imprecise and characterized by the core of a belief function, (ii) expected new data are themselves consistent with a belief function with known focal sets and (iii) the revision process is based on belief function combination. We study the properties of the information value for such a revising in the Gilboa±Schmeidler multi-prior model. Ó 2000 Elsevier Science Inc. All rights reserved.

بررسی رابطه ابهام نقش با خشنودی شغلی و عملکرد شغلی با میانجی گری رفتارهای پویای شغلی

Abstract                                                                 Introduction: Job stress such as role ambiguity, a situation that arises from the interaction between people and jobs, reduces the performance and job satisfaction. Proactive people eliminate ambiguity in their jobs by behaviors such as innovation. The present study aimed at investigating the impact of proactive person...

A Trajectory Data Clustering Method Based On Dynamic Grid Density

Under the traditional method of frequent trajectory mining, the location of data is obtained through the GPS device. However, limited equipment accuracy may incur location ambiguity. In this paper, we propose a new trajectory data clustering method based on dynamic grid density, in order to remove this ambiguity. In this method, the trajectory space of an object is firstly divided into equal-si...

Ambiguity reduction by objective model selection , with an application to the costs of the EU 2030 climate targets Richard

I estimate the cost of meeting the EU 2030 targets for greenhouse gas emission reduction, using statistical emulators of ten alternative models. Assuming a first-best policy implementation, I find that total and marginal costs are modest. The statistical emulators allow me to compute the risk premiums, which are small because the EU is rich and the policy impact is small. The ensemble of ten mo...

Near-Optimal Ambiguity Sets for Distributionally Robust Optimization

We propose a novel, Bayesian framework for assessing the relative strengths of data-driven ambiguity sets in distributionally robust optimization (DRO). The key idea is to measure the relative size between a candidate ambiguity set and an asymptotically optimal set as the amount of data grows large. This asymptotically optimal set is provably the smallest convex ambiguity set that satisfies a s...
