摘要
文章基于证券市场的多变性和存在诸多不确定性的客观事实,分析了单一证券投资技术方法的弊端,建议用多种分析方法预测证券未来的走势;引入证据理论来处理不同投资分析方法结论存在的差异;将不同的技术分析方法作为独立的证据源,用Dempster-Shafer合成法则对各种方法的结果予以融合,提高了投资分析结果的可靠性和科学性。
There are many shortcomings in the analysis of stock investment based on only one technical method for too many uncertainties exist in the stock market and the stock market itself changes constantly. In this paper, using several different methods instead of a single method is suggested. How to combine the results of different methods is really essential for different methods may get different results. So the Dempster-Shafer＇s evidence theory is introduced to combine these results. This method regards different methods as different evidence resources and the combined result is more scientific and reasonable.
