Parallel tempering for dynamic generalized linear models

ABSTRACT

Markov chain Monte Carlo (MCMC) methods can be used for statistical inference. The methods are time-consuming due to time-vary. To resolve these problems, parallel tempering (PT), as a parallel MCMC method, is tried, for dynamic generalized linear models (DGLMs), as well as the several optimal properties of our proposed method. In PT, two or more samples are drawn at the same time, and samples can exchange information with each other. We also present some simulations of the DGLMs in the case and provide two applications of Poisson-type DGLMs in financial research.     

Estimation on semi-functional linear errors-in-variables models

Abstract

Semi-functional linear regression models are important in practice. In this paper, their estimation is discussed when function-valued and real-valued random variables are all measured with additive error. By means of functional principal component analysis and kernel smoothing techniques, the estimators of the slope function and the non parametric component are obtained. To account for errors in variables, deconvolution is involved in the construction of a new class of kernel estimators. The convergence rates of the estimators of the unknown slope function and non parametric component are established under suitable norm and conditions. Simulation studies are conducted to illustrate the finite sample performance of our method.     

Testing the proportional odds model for interval-censored data

This paper discusses the goodness-of-fit test for the proportional odds model for K-sample interval-censored failure time data, which frequently occur in, for example, periodic follow-up survival studies. The proportional odds model has a feature that allows the ratio of two hazard functions to be monotonic and converge to one and provides an important tool for the modeling of survival data. To test the model, a procedure is proposed, which is a generalization of the method given in Dauxois and Kirmani [Dauxois JY, Kirmani SNUA (2003) Biometrika 90:913–922]. The asymptotic distribution of the procedure is established and its properties are evaluated by simulation studies

新文类与亚文化

新媒体和文学的结合催生出一批迥然有别于传统纸媒文学的新文类作品,而被流行化的亚文化构成了它们的重要话语资源,新文类中最常见的亚文化种类有同性恋亚文化、神秘亚文化和游戏动漫亚文化等,这些亚文化中蕴涵的抵抗和边缘因素在消费时代成为商业文化的卖点,被流行化快餐化之后作为一种＂奇观＂投合了都市青少年群体追求新奇刺激的猎奇心态,因而在新媒体平台上成为新的时尚和潮流。     

21世纪大学生心理压力探析

本文认为 ,当今大学生的心理压力主要有 3种 :大学生活的压力、个人成长的压力和社会大环境的压力。大学生活的压力包括适应的压力、学业的压力和集体生活的压力 ;个人成长的压力包括人际成长的压力、自我完善的压力、与性和爱情有关的成长压力 ;社会大环境的压力包括就业的压力、社会对人才的高要求压力和经济压力。指出进行压力处理的心理健康教育十分重要。     

跨文化意识的培养：问题与对策

在外语教学活动中，有效地培养学生的跨文化意识，增强学生的跨文化交际能力，既是教育工作者的历史使命，也是外语教学改革的一项重大课题。探索在外语教学中培养学生跨文化意识的主要途径，很有现实意义。     

中国多民族"混居"自治区域权利样态研究

多民族“混居”自治区域的各个民族政治、经济发展不平衡,历史文化也存在差异,对权利的理解和要求必然有所不同。过去我国对多民族“混居”自治区域往往重点关注政治权利的发展,对经济等权利的发展重视不够;同时多强调民族权利的共性,对各民族之间的权利差异有意无意给予回避,导致人们的权利意识发育不良。随着社会的发展,多民族“混居”自治区域的权利意识必定增长,由此也会带来权利资源的严重短缺,并引发各民族之间的权利冲突。多民族“混居”自治区域具有特殊性,其权利也应有其特殊的内容,它关系到民族的发展和国家的繁荣昌盛。     

继嗣与交换:地域社会的构成--对摩哈苴彝村的历史人类学分析

关于地域社会的构成,宗族继嗣理论注重宗族裂变的作用,社会交换理论则强调"女性交换"的意义.本文通过对摩哈苴彝村口述史材料的分析,揭示了如下两个基本事实第一,宗族裂变分支的散布与婚姻联盟的范围在地域上可以是吻合的,由此消除了继嗣理论与交换理论的对立;第二,在父系社会中,不仅存在着"男性的继嗣"与"女性的交换",而且也存在着"女性的继嗣"与"男性的交换",后者亦为地域社会构成的重要路径.
