证明了惩罚力度越大的均衡函数得到的变权向量构建的变权决策模型越偏于保守;而激励力度越大的均衡函数得到的变权决策模型越偏于乐观,这些结果与均衡函数的原始含义是一致的.最后,详细分析了几类常见的可分解均衡函数的惩罚力度和激励力度随着参数的变化情况. 相似文献

This paper studies relationships between the best linear unbiased estimators (BLUEs) of an estimable parametric functions Kβunder the Gauss-Markov model {y, Xβ, σ^2]E} and its misspecified model {y, X0β,σ^2∑0}. In addition, relationships between BLUEs under a restricted Gauss Markov model and its misspecified model are also investigated. 相似文献

The property of the material is closely related to its chemical compositions and microstruc-tures, which are the important parameters in the judgement of the quality of the material. The conventional chemical composition content of the material is an average value of the chemical composition of the whole material tested or the content of a fix position. Although it is still neces-sary to further improve these conventional methods, there are mature and systematic methods for analyzing the conve… 相似文献

In a recent paper, we proposed different relaxation procedures for optimal control problems involving time delays in the control functions. We introduced a notion of proper relaxation, applicable to problems without side constraints, where we required the minimum cost of the relaxed problem to coincide with the infimum cost of the original one. In this paper, a new and appropriate notion of relaxation for problems with side constraints is introduced. As examples of proper extensions, in the new sense, we describe in detail the standard procedure for delay-free problems and the procedure for one-delay systems which we recently proposed. 相似文献
