By taking the weight of mean-variance model as the sample information and taking the weight of market portfolio as the non-sample information,the shrinking intensity of investment weight was studied by Stein rule.
根据斯坦规则原理 ,以均值—方差模型投资权重为样本信息 ,以市场证券组合的投资权重为非样本信息 ,研究了如何确定投资权重收缩估计量的最优收缩强度 ,实现了投资组合主动管理与被动管理的有机结合。
