Functional Modelling and Classification of Longitudinal Data*

Abstract. We review and extend some statistical tools that have proved useful for analysing functional data. Functional data analysis primarily is designed for the analysis of random trajectories and infinite‐dimensional data, and there exists a need for the development of adequate statistical estimation and inference techniques. While this field is in flux, some methods have proven useful. These include warping methods, functional principal component analysis, and conditioning under Gaussian assumptions for the case of sparse data. The latter is a recent development that may provide a bridge between functional and more classical longitudinal data analysis. Besides presenting a brief review of functional principal components and functional regression, we develop some concepts for estimating functional principal component scores in the sparse situation. An extension of the so‐called generalized functional linear model to the case of sparse longitudinal predictors is proposed. This extension includes functional binary regression models for longitudinal data and is illustrated with data on primary biliary cirrhosis.     

Reproducibility of clinical data I: continuous outcomes

Across a variety of clinical settings, repeated measurements on an individual, obtained under identical circumstances, often differ from one another. This implies the measurements lack perfect reproducibility. Topics related to reproducibility of clinical measurements are introduced in this paper. In this first of two parts, continuous outcomes are addressed. The intraclass correlation coefficient, ρ, has been the traditional coefficient of reproducibility for continuous outcomes. The importance of ρ regarding observations on an individual, and observations among populations, is outlined. Estimation and inferential procedures for ρ are reviewed and worked examples are provided. Copyright © 2004 John Wiley & Sons, Ltd.     

Stress Hormone Changes and Marital Conflict: Spouses’ Relative Power Makes a Difference

We investigated the impact of relative marital power on 72 newlywed couples’ endocrinological responses to marital conflict. Marital power was determined by comparing spouses’ reports of dependent love for one another. Less powerful spouses displayed elevated adrenocorticotropic hormone (ACTH) responses to a conflict discussion. Shared power appeared to have a beneficial effect on wives’ but not husbands’ ACTH responses. Spouses’ cortisol levels declined over time, except for wives who were less powerful and for husbands who shared power with their wives. Conflict behaviors did not differ as a function of this marital power index. These data suggest that relative levels of general emotional power in relationships may play an important role in spouses’ physiological responses to marital conflict.     

对我国企业统计制度方法改革的若干思考

企业统计作为政府宏观统计信息的源头，不仅是国民经济统计工作的基础．而且还是政府和企业科学决策的基础。改革我国企业统计制度方法，要坚持树立科学发展观，实现企业统计制度创新；要注意与部门统计、专业统计的协调；要加强企业统计基础和统计队伍建设；可以官方统计与非官方统计相结合；要建立和完善服务业企业经常性统计调查方法制度。

当代高等教育历史叙事的转换与学生管理工作协动平台的构建

本文采用文献资料、逻辑分析的方法,分析了我国当代社会文化的趋势以及这种文化转型对高校学生管理工作的影响,探讨了新的学生管理协动平台的特征。文章认为当代教育的历史叙事以转向“人的全面发展,”以“导师制度——辅导员制度——学生自我管理制度”为主体的多级协动管理平台的建构,将推动高校学生管理工作的进一步发展。     

组合投资的非均衡性研究

爱·受苦·悲悯与人格——曹禺《雷雨》悲悯情怀的文化阐释

在曹禺精心营造的以《雷雨》为代表的戏剧世界里,弥漫着强烈的悲剧色彩,灌注着浓郁的悲悯情怀。人生历程中的苦痛所产生的悲苦感受与自我悲悯,让曹禺产生了"生存之畏",这种"生存之畏"又使得曹禺在潜意识里把个体导向了人类群体,转向了对人生、甚至对整个宇宙天地的同情与怜悯,从而显现出一种人文主义的关怀和悲天悯人的情怀。这种人性光辉下蕴含的心灵状态是高尚人格的基本标志,其深刻的内涵,是博大的胸怀、仁爱的情感。这些构成了曹禺作品人文主义的思想意蕴和超越世俗的审美价值。
