Some properties of conditional entropy, information quantity and EVSI of sample information with distinct accuracy are discussed.

文摘In this paper, two new computing formulas of maximal expected monetary value EMV * s in Bayesian analysis have been derived. Then, the definitions of conditional entropy, information quantity of sample information have been given. Some properties of conditional entropy, information quantity and EVSI of sample information with distinct accuracy are discussed. Finally, for the situation that there exist two states in state space, the influences of changes of accuracy of information on EMV * s and EVSI are studied. Conclusions have been obtained that EMV * s and EVSI are monotone non decreasing as the sample information becomes more strictly accurate.
