一类随机利率下的增额寿险 总被引:6,自引:0,他引:6
寿险中的利率随机问题,是近来保险精算研究的热点和重点问题之一。本以即时给付的一类增额寿险为对象,对随机利率采用Gauss过程建模,研究给付现值及其各阶矩。 相似文献

In this paper, we study the problems of optimal allocation of policy limits and deductibles. Several objective functions are considered: maximizing the expected utility of wealth assuming the losses are independent, minimizing the expected total retained loss and maximizing the expected utility of wealth when the dependence structure is unknown. Orderings of the optimal allocations are obtained. 相似文献

Using symmetric function theory, we study the cycle structure and increasing subsequence structure of permutations after iterations of various shuffling methods. We emphasize the role of Cauchy type identities and variations of the Robinson-Schensted-Knuth correspondence. 相似文献

Let A be a nonempty real central arrangement of hyperplanes and Ch be the set of chambers of A. Each hyperplane H defines a half-space H+ and the other half-space H−. Let B={+,−}. For H∈A, define a map by (if C⊆H+) and (if C⊆H−). Define . Let Chm=Ch×Ch×?×Ch (m times). Then the maps induce the maps . We will study the admissible maps which are compatible with every . Suppose |A|?3 and m?2. Then we will show that A is indecomposable if and only if every admissible map is a projection to a component. When A is a braid arrangement, which is indecomposable, this result is equivalent to Arrow's impossibility theorem in economics. We also determine the set of admissible maps explicitly for every nonempty real central arrangement. 相似文献

In this article, we consider a stationary α-mixing random field in IR
d. Under a large-sample scheme that is a mixture of the so-called “infill” and “increasing domain” asymptotics, we establish
a functional central limit theorem for the empirical processes of this random field. Further, we apply a blockwise bootstrap
to the samples. Under the condition that the side length of the block
for some 0 < β < 1, where λ
n
is the growth rate in the increasing domain asymptotics, we show that the bootstrapped empirical process converges weakly
to the same limiting Gaussian process almost surely. Extension to multivariate random fields and application to differentiable
statistical functionals are also given. A spatial version of the Bernstein’s inequality is developed, which may be of some
independent interest.

Which collections of mn minors of an m-by-n matrix uniquely determine the matrix, given some regularity conditions? For m=n=3, the 585 such collections, that are distinct up to symmetry, are determined. For general m, n, a necessary and a sufficient condition for reconstruction are given in terms of matchings in a bipartite graph. Among other particular results, those collections of entries for which there are minors that permit reconstruction one entry at a time are characterized. 相似文献
