Summary The error bound of an approximation to the distribution of thekth largest order statistic as established by Reiss (1981,Adv. Appl. Prob.,13, 533–547) is improved by making use of an asymptotic expansion of length two in Reiss (the same as above). 相似文献

Let n denote the sample size, and let ri ∈ {1,…,n} fulfill the conditions ri ? ri?1 ≥ 5 for i = 1,…,k. It is proved that the joint normalized distribution of the order statistics Zri:n, i = 1,…,k, is independent of the underlying probability measure up to a remainder term of order . A counterexample shows that, as far as central order statistics are concerned, this remainder term is not of the order if ri ? ri?1 = 1 for i = 2,…,k. 相似文献

The reactions 72, 74, 76Ge(3He, d) were investigated at Elab = 23 MeV with a multigap and a Q3D magnetic spectrograph. Some 30 new levels up to have been found. The level schemes of the odd As isotopes 73, 75, 77As up to seem to be rather independent of the neutron number. The good agreement of the low-lying level structure with the Coriolis-coupling model including a pairing force was verified and the vacancies of low-lying shell model states were extracted and compared with the simple pairing theory. 相似文献

We present the first solid-state NMR experiments developed using optimal control theory. Taking heteronuclear dipolar recoupling in magic-angle-spinning NMR as an example, it proves possible to significantly improve the efficiency of the experiments while introducing robustness toward instrumental imperfections such as radio frequency inhomogeneity. The improvements are demonstrated by numerical simulations as well as practical experiments on a 13Calpha,15N-labeled powder of glycine. The experiments demonstrate a gain of 53% in the efficiency for 15N to 13Calpha coherence transfer relative to the typically double-cross-polarization experiments. 相似文献

A penalized approach is proposed for performing large numbers of parallel nonparametric analyses of either of two types: restricted likelihood ratio tests of a parametric regression model versus a general smooth alternative, and nonparametric regression. Compared with naïvely performing each analysis in turn, our techniques reduce computation time dramatically. Viewing the large collection of scatterplot smooths produced by our methods as functional data, we develop a clustering approach to summarize and visualize these results. Our approach is applicable to ultra-high-dimensional data, particularly data acquired by neuroimaging; we illustrate it with an analysis of developmental trajectories of functional connectivity at each of approximately 70,000 brain locations. Supplementary materials, including an appendix and an R package, are available online. 相似文献

Tris(diisopropylammonium)tetrachloridoferrate(III) dichloride crystallizes in the monoclinic space group P21/c (a = 7.6685(2) ?, b = 17.6079(3) ?, c = 23.3217(4) ?, β = 91.396(2)°, V = 3148.1(1) ?3, Z = 4, T = 113 K) with three diisopropylammonium cations (dip), one tetrachloridoferrate(III) anion, and two chloride anions in the asymmetric unit. The dip cations and the chloride anions form hydrogen bonded one-dimensional polymers along [010]. The tetrachloridoferrate(III) anion, habituated in between these chains, is not involved in any hydrogen bonding. The structural characterization is supported by infrared and Raman spectroscopic data. 相似文献
