Computer-Generated Neighbor Designs

Neighbor designs are useful to remove the neighbor effects. In this article, an algorithm is developed and is coded in Visual C + +to generate the initial block for possible first, second,…, and all order neighbor designs. To get the required design, a block (0, 1, 2,…, k ? 1) is then augmented with (v ? 1) blocks obtained by developing the initial block cyclically mod (v ? 1).     

Convolution of Binomial and Negative Binomial Variables

This paper considers a distribution formed by convolution of binomial and negative binomial variables. The distribution has the flexibility to adapt to the model under, equi, and over dispersion. Some properties of the proposed distribution are discussed, including characterization. Three stochastic processes leading to the distribution are also considered: (1) a three-dimensional random walk; (2) a birth, death, and immigration process; and (3) a thinned stochastic process.     

从地缘政治角度看冷战后中蒙关系

中国的北部邻国蒙古,从地缘政治角度看,其地处亚洲大陆中部,仅有两个邻国,中国、俄罗斯,地缘战略位置极为重要。冷战结束后中蒙两国关系平稳健康发展,双方高层互访频繁,经贸往来规模不断扩大。随着蒙古国政治、经济领域改革的深入和“多支点”外交政策的出台,尤其是“第三邻国”的进人使各国在蒙古境内包括能源等领域的竞争日益激烈,中国北部面临的地缘政治环境发生了复杂微妙的变化。     

基于稳定的车联网最佳中继节点选择

在车联网中，用户节点通过中继节点与Sink节点建立连接并传输信息时，存在端对端吞吐量较小的问题.本文提出了一种基于稳定的车联网最佳中继节点选择方案，在对车辆节点的位置建立模型的基础上，结合车辆在运行中的稳定性因素，最终通过选取最佳中继节点来提高节点之间的吞吐量，并对该方案进行了仿真实验.实验证明了该方案的有效性，提高了节点间的吞吐量.     

Simple constructions for minimal neighbor and GN2 designs in linear blocks

Minimal neighbor designs and GN₂ designs in linear blocks are constructed for all admissible parameter sets. The method is straightforward and uses subsequences of the LWW terrace as initial blocks from which the remaining blocks are generated.     

论行动研究方法在反腐败领域的运用

行动研究作为一种扎根于真实情境的研究方法,其在反腐败领域的运用,具有独特的价值。既可以解决反腐败一线工作中的问题,提高反腐败工作的质量及一线工作者的业务素质,促进其职业发展;又可以在强化反腐败一线工作者的职业意识、增强其职业成就感的同时,推进反腐败研究范式的变革,推动反腐败理论的发展。在反腐败领域引入行动研究方法的关键节点主要包括研究的出发点、研究的实施者、研究的全过程以及研究成果的运用等。而将反腐败领域引入行动研究方法应注意的事项主要有三,即尽可能通过多种途径发现反腐败实践中存在的问题,尽可能采取多种方式开展合作研究,尽可能推进多维度的行为反思等。     

Proper generalized neighbor designs in circular blocks

Generalized neighbor designs relax the condition of constancy on the number of times two treatments occur as neighbors in a design. In this paper, we constructed generalized neighbor designs in circular blocks of equal size. Catalogs of these designs for block size 5, 7 and 9 are also compiled. All the designs given here are binary.

基于最少节点的非圆曲线拟合方法

介绍了一种基于最少节点的直线拟合非圆曲线新方法，它采用面积偏差来分析、评价拟合误差，在节点计算时用最大偏差来控制拟合误差。拟合误差一定时，这种方法具有节点数少、计算工作量小和编程简便等优点     

A fully nonparametric diagnostic test for homogeneity of variances

The authors propose a new nonparametric diagnostic test for checking the constancy of the conditional variance function σ²(x) in the regression model Y_i = m(x_i) + σ(x_i)?_i, i = 1,…, m. Their test, which does not assume a known parametric form for the conditional mean function m(x), is inspired by a recent asymptotic theory in the analysis of variance when the number of factor levels is large. The authors demonstrate through simulations the good finite‐sample properties of the test and illustrate its use in a study on the effect of drug utilization on health care costs.
