摘要 利用最优估计理论中常用的卡尔曼滤波方法对β系数进行实时估计和预测估计,并将其估计结果与传统的回归分析方法的估计结果进行比较.实证结果充分体现出卡尔曼滤波方法在证券投资分析中的优越性. The Kalman filtering theory allows us to obtain the real-time estimation and the prediction estimation of the β. Then it is reported that the results of this method increase greatly in precision compared with the traditional regression method, which demonstrates the advantage of Kalman filtering theory.
