A Semi-Parametric Quantile Function Estimator for Use in Bootstrap Estimation Procedures

In this note we develop a new quantile function estimator called the tail extrapolation quantile function estimator. The estimator behaves asymptotically exactly the same as the standard linear interpolation estimator. For finite samples there is small correction towards estimating the extreme quantiles. We illustrate that by employing this new estimator we can greatly improve the coverage probabilities of the standard bootstrap percentile confidence intervals. The method does not reqiure complicated calculations and hence it should appeal to the statistical practitioner.     

近代河南集市研究再思考

近代集市的发展不仅表现为数量方面的增加,也有集市数量不变而集市承载量增加的情况;考察集市分布密度以耕地面积为基础更有可比性,而且开市率的高低主要是人们传统习惯、人口规模、集市密度、商品化程度、经济发展状况等因素综合作用的结果,其中传统习惯对开市率的影响较大。     

整代数体函数的亏量

研究了一类具有v＋1个亏值的v-值整代数体函数，利用整代数体函数的级与特征函数及其亏值亏量的定义和性质，借助线性无关性、克兰姆法则、Jensen公式及对数导数定理进行分析推理，得出这类整代数体函数的所有亏量之和不超过v．     

从殖民和后殖民的角度看现代性问题

全球范围内殖民主义体系的崩溃，使现代性具有了多义性和混乱性。这证明了西方现代性本身存在着矛盾性和含混性，也说明了西方现代性的对立面——反殖民主义和现代性的效颦者——更加深了现代性本身的矛盾性和含混性，表现出对资本主义工业（或后工业）社会所设想的现代文明的质疑与抗议。     

A circular-cone test for testing homogeneity against a simple tree order

Several methods exist for the problem of testing the equality of several treatments against the one-sided alternative that the treatments are better than the control. These methods include Dunnett's test, Bartholomew's likelihood-ratio test, the Abelson-Tukey-Schaafsma-Smid optimal-contrast test, and the multiple-contrast test of Mukerjee, Robertson, and Wright. A new test is proposed based on an approximation of the likelihood-ratio test of Bartholomew. This test involves using a circular cone in place of the alternative-hypothesis cone. The circular-cone test has excellent power characteristics similar to those of Bartholomew's test. Moreover, it has the advantages of being simpler to compute and may be used with unequal sample sizes.     

教育失序问题的文化救治（上）

教育发展、人的自由而全面的发展与教育秩序的矛盾．是人们在现代社会生活中所必然遇到的一个基本问题。这在教育的现代转型中表现得尤为明显。虽然解答这一问题的根本思路是加强教育制度建设，但由于文化有其特殊的公共性，因而也是解答现代社会教育发展、人的自由而全面发展与教育秩序问题的一条重要理路。在现代教育制度的架构下，通过帮助人们获得公共价值观、起码共识和基本共同感，文化构成现代社会教育发展、人的自由而全面发展不可或缺的重要机制。     

Expected sample moments of concomitants of selected order statistics

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determined numerically are obtained. While the results are exact only for normal populations, it is shown experimentally that including skewness and kurtosis in the calculations can yield greatly improved results for other distributions.     

信任与秩序——和谐社会的政治分析
