摘要翻译:
通过对线性置信函数概念的阐述(Dempster1990;Liu1996),我们提出了一种用线性置信函数表示专家系统知识的基本方法。我们展示如何使用基本矩阵来表示市场信息和金融知识,包括完全无知、统计观察、主观推测、分布假设、线性关系和经验资产定价模型。然后,我们利用Dempster的组合规则来整合知识来评估投资组合绩效的整体信念,并通过整合额外的信息来更新信念。我们用三只黄金股票的例子来说明这种方法。

英文摘要:
By elaborating on the notion of linear belief functions (Dempster 1990; Liu 1996), we propose an elementary approach to knowledge representation for expert systems using linear belief functions. We show how to use basic matrices to represent market information and financial knowledge, including complete ignorance, statistical observations, subjective speculations, distributional assumptions, linear relations, and empirical asset pricing models. We then appeal to Dempster's rule of combination to integrate the knowledge for assessing an overall belief of portfolio performance, and updating the belief by incorporating additional information. We use an example of three gold stocks to illustrate the approach.
