摘要
提出了(Be-G)决策模型,给出了二行动线性决策模型的一般形式,讨论了此模型下二行动线性决策问题的抽样信息期望值(EVSI)的计算问题,得到了此决策问题的最优决策函数,进而给出了EVSI的计算公式.
The (Be-G) decision model is presented, gives the general form of linear decision problem on two actions under the model, and how to calculate the expected value of sampling information(EVSI) for linear decision problem on two actions under the model is discussed. By calculating the posterior distribution of the parameter,the choosing criteria about the best posterior actions is set up,and the best decision function is obtained. Finally,the counting formula of EVSI is given.
