| Abstract: | 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. |
