统计预测问题的决策影响图方法
STATISTICAL PREDICTION BY THE METHOD OF DECISION INFLUDNCE DIAGRAMS
【摘要】 结合线性回归模型,运用决策分析中的影响图方法,求解一类统计预测问题。该法不需估计线性回归模型中的未知参数a和β只利用(a,β)的联合分布。最后,将该法推广到更一般的预测问题。
【Abstract】 n statistics,we usually make statistical prediction by using the regetrssionanalysis,particulary in the case where the system model is linear.This papor combines the linearregression model with the iufluence diagram method which is a new method of decision analysis,andmakes the statistical prediction from the view of decision. This method need not estimate the unknownparamter a and β in the linear regression model,and only need to use the joint distributionp(a,β). Finally,this method is exended to more general statistical prediction cases.
