Three-part model for fractional response variables with application to Chinese household health insurance coverage

A survey on health insurance was conducted in July and August of 2011 in three major cities in China. In this study, we analyze the household coverage rate, which is an important index of the quality of health insurance. The coverage rate is restricted to the unit interval [0, 1], and it may differ from other rate data in that the “two corners” are nonzero. That is, there are nonzero probabilities of zero and full coverage. Such data may also be encountered in economics, finance, medicine, and many other areas. The existing approaches may not be able to properly accommodate such data. In this study, we develop a three-part model that properly describes fractional response variables with non-ignorable zeros and ones. We investigate estimation and inference under two proportional constraints on the regression parameters. Such constraints may lead to more lucid interpretations and fewer unknown parameters and hence more accurate estimation. A simulation study is conducted to compare the performance of constrained and unconstrained models and show that estimation under constraint can be more efficient. The analysis of household health insurance coverage data suggests that household size, income, expense, and presence of chronic disease are associated with insurance coverage.

健康在多大程度上引致贫困脆弱性——基于CHNS农村数据的经验分析

贫困脆弱性的产生,很大程度上归因于居民健康水平的下降.在阐述健康引致贫困理论机制的基础上,基于CHNS在2000-2009年间追踪调查数据,对贫困脆弱性和健康效用指数HUI进行测度,估计并分析健康对贫困脆弱性的影响与内在机制.研究发现:居民健康水平的恶化会使其面临更高的贫困脆弱性,居民健康水平每下降10％,贫困脆弱性大约会上升6％;健康影响贫困脆弱性的作用机制中,物质资本和社会资本渠道被证明是相对有效的,而人力资本渠道尽管体现出微弱效应,但尚未在统计上得到显著性验证.因此,制订前瞻性的反贫政策应着眼于建立健康风险防范机制,包括提高农村医疗保障水平和重大疾病救助力度,并增加农村公共服务的投入,以促进其均衡化发展.     

Bill Cochran: His Contributions to Medicine and Public Health and Some Personal Recollections

There is a tremendous need in our technological society to train statisticians for all sectors of education, government, and industry. Because statistical training has largely been restricted to graduate schools, the profession is losing many good students to other fields of study. Members of the statistics community are encouraged to reach out to high-school students and undergraduate students to increase the awareness of statistics as a scientific field of study and as a professional career. The ASA Council of Chapters has recently completed a slide presentation entitled “Statistical Science: The Profession,” which was professionally developed to aid this endeavor. In addition, high-school teachers, high-school counselors, and professors of mathematics and science education are identified as important audiences for hearing this message and for broadening general public awareness of what our profession has to offer.     

A case–control study relating railroad worker mortality to diesel exhaust exposure using a threshold regression model

A case–control study of lung cancer mortality in U.S. railroad workers in jobs with and without diesel exhaust exposure is reanalyzed using a new threshold regression methodology. The study included 1256 workers who died of lung cancer and 2385 controls who died primarily of circulatory system diseases. Diesel exhaust exposure was assessed using railroad job history from the US Railroad Retirement Board and an industrial hygiene survey. Smoking habits were available from next-of-kin and potential asbestos exposure was assessed by job history review. The new analysis reassesses lung cancer mortality and examines circulatory system disease mortality. Jobs with regular exposure to diesel exhaust had a survival pattern characterized by an initial delay in mortality, followed by a rapid deterioration of health prior to death. The pattern is seen in subjects dying of lung cancer, circulatory system diseases, and other causes. The unique pattern is illustrated using a new type of Kaplan–Meier survival plot in which the time scale represents a measure of disease progression rather than calendar time. The disease progression scale accounts for a healthy-worker effect when describing the effects of cumulative exposures on mortality.

“边缘化”大学生个体成因、预防与矫治的研究

＂边缘化＂学生是指行为超出正常规范、学业严重不佳的学生个体。认为中学及大学阶段的管理、社会因素、理想与现实的错位以及个人性格心理特点等是形成＂边缘化＂学生个体的主要原因;管理者建立＂防边缘化＂预警机制、抓住管理的关键时期及努力营造良好学风是有效预防＂边缘化＂的措施;选择适当的角度和有效的工作方法可以对＂边缘化＂学生完成成功矫治。
