By modifying the method of projection, the results of Hajek and Huskova are extended to show the asymptotic normality of signed and linear rank statistics under general alternatives for dependent random variables that can be expressed as independent vectors of fixed equal length. The score function is twice differentiable; the regression constants are arbitrary; and the distribution functions are continuous, but arbitrary. As an application, a rank transform statistic is proposed for the one-sample multivariate location model. The ranks of the absolute values of the observations are calculated without regard to component membership, and the scored ranks are substituted in place of the observed values. The limiting distribution of the proposed test statistic is shown to be χ2 divided by the degrees of freedom under the null hypothesis, and noncentral χ2 divided by the degrees of freedom under the sequence of Pitman alternatives. 相似文献

《Statistics & probability letters》1990,10(5):381-390Let Dn,r denote the largest rth nearest neighbor link for n points drawn independently and uniformly from the unit d-cube Cd. We show that according as r < d or r>d, the limiting behavior of Dn,r, as n → ∞, is determined by the two-dimensional ‘faces’ respectively one-dimensional ‘edges’ of the boundary of Cd. If d = r, a ‘balance’ between faces and edges occurs. In case of a d-dimensional sphere (instead of a cube) the boundary dominates the asymptotic behavior of Dn,r if d 3 or if d = 2, r 3. 相似文献

In this paper, Bayesian linear prediction of the total of a finite population is considered in situations where the observation error variance is parameter dependent. Connections with least squares prediction (Royall (1976, J. Amer. Statist. Assoc., 71, 657–664)) in mixed linear models (Theil (1971, Principles of Econometrics, Wiley, New York)), are established. Extensions to the case of dynamic (state dependent) superpopulation models are also proposed. 相似文献

For the scalar reaction diffusion equation with Dirichlet boundary conditions, it is proved that its maximal compact attractor is the graph of a C1 function from a subset with nonempty interior of a subspace of the state space the dimension of which is equal to the maximal Morse index of the equilibria of the equation. 相似文献

转动传能中的量子干涉--干涉角和转动量子数的关系 总被引:9,自引:9,他引:0
沙国河等人在CO(A1∏(v=0)~e3∑-(v=1))体系与He,Ne和Ar碰撞诱导转动传能中首次观测到了量子干涉效应,并测量了干涉度。从理论上进一步研究原子-双原子分子体系碰撞诱导转动传能中量子干涉效应与转动量子数以及能量间隔的关系是十分必要的。我们考虑长程相互作用势,应用一级玻恩近似和直线轨迹近似,分别计算了CO(A1∏(v=0)~e3∑-(v=1))体系和He,Ne,Ar碰撞诱导转动传能中不同转动量子数以及不同能量间隔下的干涉角,得到了干涉角随转动量子数和能量间隔的变化趋势。这些结果对设计、分析这种类型的实验有一定的指导意义。 相似文献

For each pair of linear orderings (L,M), the representability number reprM(L) of L in M is the least ordinal α such that L can be order-embedded into the lexicographic power . The case is relevant to utility theory. The main results in this paper are as follows. (i) If κ is a regular cardinal that is not order-embeddable in M, then reprM(κ)=κ; as a consequence, for each κω1. (ii) If M is an uncountable linear ordering with the property that A×lex2 is not order-embeddable in M for each uncountable AM, then for any ordinal α; in particular, . (iii) If L is either an Aronszajn line or a Souslin line, then . 相似文献

Electromigration experiments of ionic surfactants were performed by using a capillary tube isotachophoretic apparatus. The zone of the migrated surfactant was collected after separation, and the surfactant concentration of the migrated zone was determined by HPLC analysis. The surfactant concentration of the migrated zone was increased with an increase in electrolyte concentration, and was in accord with the prediction of the Kohlrausch equation. When the electrolyte concentration further increased, the surfactant molecules began to migrate as a micellar state. Moreover, the mixed systems of ionic-non ionic and ionic-ionic surfactants were also examined and revealed the migration as mixed micelle. 相似文献
