Inference about parameters in Binomial-Poisson distribution with additional incomplete data

ABSTRACT

This article considers the distribution of Binomial-Poisson random vector which has two components and includes two parameters: one is the rate of a Poisson distribution, the other is the proportion in a Binomial distribution. The inference about the two parameters is usually made based on only paired observations. However, the number of paired observations is, in general, not large enough because of either technical difficulty or budget limitation, and so one can not make efficient inferences with only paired data. Instead, it is often much easier and not too costly to have incomplete observation on only one component independently. In this article we will combine both the paired complete data and unpaired incomplete data for estimating the two parameters. The performances of various estimators are compared both analytically and numerically. It is observed that fully using the unpaired incomplete data can always improve the inference, and the improvement is very significant in the case when there are only a few paired complete observations.

Assessment of the Effect of Population and Diary Sampling Methods on Estimation of School‐Age Children Exposure to Fine Particles

Population and diary sampling methods are employed in exposure models to sample simulated individuals and their daily activity on each simulation day. Different sampling methods may lead to variations in estimated human exposure. In this study, two population sampling methods (stratified‐random and random‐random) and three diary sampling methods (random resampling, diversity and autocorrelation, and Markov‐chain cluster [MCC]) are evaluated. Their impacts on estimated children's exposure to ambient fine particulate matter (PM_2.5) are quantified via case studies for children in Wake County, NC for July 2002. The estimated mean daily average exposure is 12.9 μg/m³ for simulated children using the stratified population sampling method, and 12.2 μg/m³ using the random sampling method. These minor differences are caused by the random sampling among ages within census tracts. Among the three diary sampling methods, there are differences in the estimated number of individuals with multiple days of exposures exceeding a benchmark of concern of 25 μg/m³ due to differences in how multiday longitudinal diaries are estimated. The MCC method is relatively more conservative. In case studies evaluated here, the MCC method led to 10% higher estimation of the number of individuals with repeated exposures exceeding the benchmark. The comparisons help to identify and contrast the capabilities of each method and to offer insight regarding implications of method choice. Exposure simulation results are robust to the two population sampling methods evaluated, and are sensitive to the choice of method for simulating longitudinal diaries, particularly when analyzing results for specific microenvironments or for exposures exceeding a benchmark of concern.     

黑龙江省水稻国际竞争力影响因素分析

从2005年开始,我国农业在加入WTO谈判中争取的过渡期基本结束,中国大米在价格方面的传统优势正在丧失,作为我国最大的优质商品水稻基地的黑龙江省,面临进出口配额逐步取消、关税降低,国外竞争压力不断加大的局面,为此,分析黑龙江省水稻国际竞争力影响因素、主动发挥稻谷产业的优势,提高黑龙江省水稻的国际竞争力,抵御国外同类产品的冲击值得人们思考。     

大学新生留降级现状分析及对策研究

为实现高等教育“规模与质量”的和谐统一,达到提高大学教学质量的目的。本文通过对近几年来留降级情况和学位授予情况统计表明,大学一年级新生留降级比率大大高于高年级的留降级比率,新生学习状况对授予学士学位有很大影响。经过从教育方式、方法、学生的心理素质、认识能力、专业思想以及人生观、价值观等方面认真而深入的分析,提出了转变观念、改革现行应试教育体制、提高教师的业务水平,改变现行招生模式、实行以学院为基本单位的大类招生、建立指导教师制度等对策。

我国地方财政支出结构与地方经济增长关系的实证研究

地方财政支出在我国地方经济增长中有着非常重要的作用,对地方财政支出结构与地方经济增长关系的研究有助于更好地理解地方财政支出的经济增长效应.利用省际面板数据(Panel Data)对我国地方财政支出结构与地方经济增长关系的实证分析表明,东部、中部和西部地区的地方财政支出结构存在着不同的经济增长效应;我国地方财政支出结构的不合理在一定程度上制约着地方财政支出经济增长效应的发挥.     

教师人格魅力在“思想道德修养与法律基础”课教学中的作用探析

提高教育教学质量的一个重要因素在教师,在于教师的人格魅力。＂思想道德修养与法律基础＂课教师具有＂传道授业解惑＂的职责,他们在教会学生做人、做事,扮演着＂立德＂＂立志＂＂立人＂的角色的同时,彰显求真、至善、唯美的统一的人格魅力。在＂基础＂课的教学中,＂基础＂课教师的人格魅力有助于提高＂基础＂课教学实效性,加深学生对＂基础＂课教学的认同感,对学生人格发展和意志品质的形成起着重要作用。
