Without assuming that the level sets ofpenalty functions are weakly compact, a fixed representative pair (P∗,Q∗) is found by a newmethod different from the convex duality method. Then we show that the optimal testsare just the classical Neyman-Pearson tests between the representative probabilitiesP∗ and Q∗. Finally, we apply our results to a shortfall risk minimizingproblem in an incomplete financial market. 讲座主持:闫理坦教授 撰写:李学元 |
