正态分布在投资决策中的应用

在投资决策中，经常会遇到需要在不确定状态下决策的问题，在此情况下，单凭主观经验或客观资料做资料做决策，其盲目性和风险性均较大。如果在做决策之前进行某种抽样实验，得根据抽样结果所提供的信息对影响的各种自然状态增加了解后再做决策，可以提高决策的正确性，本文对如何应用正态分布，求出最优化决策行动的问题进行了探讨。

The Application of The Normal Distribution in Investment Decision

in the decision of investorment, we are often faced with the problem of decision-making under uncertainty states. In this case, if we make decision only by objective experiences or subjective data, it has much blindness and risk. If we do some sampling experiments before making decision, the decision-maker makes decision after the further comprehension of the natural states which influence the decision-making according to the information proveded by sampling results, it will improve the property of the decision. This paper discussed how to apply normal distribution to solve the optimal decision problem.
