| 摘 要： | 从主客观概率之争入手,结合现实金融资产投资中概率分布的不可知性,讨论金融资产投资分析中的概率分布设定风险,同时借用贝叶斯学习过程与序贯决策策略,探讨概率分布设定风险的控制与投资决策的优化。分析结论认为,基于贝叶斯分析的序贯决策,无论在提升期望收益方面,还是在控制概率分布设定风险方面都是有效的。 |
| 关 键 词： | 概率分布设定风险 状态空间 贝叶斯分析 序贯决策 |

| Abstract: | Starting with the controversy of subjective probability and objective probability and combining with the unknowable probability distribution of financial asset investment in reality,we discuss the suppose risk of probability distribution in the analysis of financial asset investment.At the same time we explore the control of the suppose risk of probability distribution and the optimizing of investment decision by Bays learning process and sequence decision.The conclusion is that sequence decision based on Bays analysis is effective not only on improving the expected income and but also on controlling the suppose risk of probability distribution. |
| Keywords: | suppose risk of probability distribution state space Bays analysis sequence decision |
