The Design of Scoring Schemes for Surveys Using the Block Total Response Method

ABSTRACT

In this article we investigate the design of scoring schemes for surveys using the block total response method. This method was first proposed by Raghavarao and Federer (1979 Raghavarao , D. , Federer , W. T. ( 1979 ). Block total response as an alternative to the randomized response method in surveys . J. Roy. Statist. Soc. 41 ( 1 ): 40 – 45 . [CSA] [CROSSREF]  [Google Scholar]) to provide accurate estimates of the base rates of sensitive characteristics using balanced incomplete block designs. The scoring scheme used in Raghavarao and Federer (1979 Raghavarao , D. , Federer , W. T. ( 1979 ). Block total response as an alternative to the randomized response method in surveys . J. Roy. Statist. Soc. 41 ( 1 ): 40 – 45 . [CSA] [CROSSREF]  [Google Scholar]) did not guarantee anonymity of answers and so the possibility of improving on this basic scoring scheme is considered in this article.     

The generalized two-sided power distribution

The generalized standard two-sided power (GTSP) distribution was mentioned only in passing by Kotz and van Dorp Beyond Beta, Other Continuous Families of Distributions with Bounded Support and Applications, World Scientific Press, Singapore, 2004. In this paper, we shall further investigate this three-parameter distribution by presenting some novel properties and use its more general form to contrast the chronology of developments of various authors on the two-parameter TSP distribution since its initial introduction. GTSP distributions allow for J-shaped forms of its pdf, whereas TSP distributions are limited to U-shaped and unimodal forms. Hence, GTSP distributions possess the same three distributional shapes as the classical beta distributions. A novel method and algorithm for the indirect elicitation of the two-power parameters of the GTSP distribution is developed. We present a Project Evaluation Review Technique example that utilizes this algorithm and demonstrates the benefit of separate powers for the two branches of activity GTSP distributions for project completion time uncertainty estimation.     

Reliability analysis for stress-strength model from a general family of truncated distributions under censored data

Abstract

Under progressive Type-II censoring, inference of stress-strength reliability (SSR) is studied for a general family of lower truncated distributions. When the lifetime models of the strength and stress variables have arbitrary and common parameters, maximum likelihood and pivotal quantities based generalized estimators of SSR are established, respectively. Confidence intervals are constructed based on generalized pivotal quantities and bootstrap technique under different parameter cases as well. In addition, to compare the equivalence of the strength and stress parameters, likelihood ratio testing of interested parameters is provided as a complementary. Simulation studies and two real-life data examples are provided to investigate the performance of proposed methods.     

正交试验法在光学系统公差设计中的应用

本文为光学系统的公差制定提供了一种新方法,即用正交试验法合理地选择最优的公差组合,对象差进行补偿。此种方法制定的公差不仅指出了象差补偿的最佳公差趋向,而且为在满足成象要求的前提下放宽公差提供了可能。文章对参数的初始公差计算在松居法的基础上作了改进,阐述了应用正交试验法制定公差的前提及基本过程,并列举了一个三片型照相物镜的计算实例。

网格服务在我国的普及之路

网格服务目前正以爆炸式增长势头向前发展。世界各国政府及跨国IT公司也都纷纷推出计算机网格发展计划及方案,我国目前也有相应的计划,但缺乏商用市场解决方案,很难在市场上得到普及,所以,大力开发实用解决方案是网格普及的必由之路。     

县域经济衰落的原因分析与治理思路

中国落后的小县城面临着严重的经济问题,如企业缺乏发展,投资经营环境差,企业生存率低,失业率高和人力资源外流等.主导产业衰落和产业结构单一是县域经济落后的顽疾与症结所在,另外缺乏知识、技能基础和政府的合理规划也是重要影响因素.治理县域经济衰落应从奠定高起点的知识和技能入手,培育新兴主导产业部门,形成"增长极",推动相关产业的聚集和发展,从而带动落后县域摆脱贫困.
