The Planning Stage in Statistical Reasoning

An important step in the statistical problem-solving process is the selection of the appropriate statistical procedure for the real-world situation under analysis. A decision-tree term project has been found to be an effective teaching device to help MBA students understand this step. The project requires the students to construct a decision-tree structure, which, through a series of questions and responses, will lead from the statement of a statistical question to the appropriate sampling distribution to use in addressing the question.

A Weighting Approach for GEE Analysis with Missing Data

We propose a new weighting (WT) method to handle missing categorical outcomes in longitudinal data analysis using generalized estimating equations (GEE). The proposed WT provides a valid GEE estimator when the data are missing at random (MAR), and has more stable weights and shows advantage in efficiency compared to the inverse probability weighing method in the presence of small observation probabilities. The WT estimator is similar to the stabilized weighting (SWT) estimator under mild conditions, but it is more stable and efficient than SWT when the associations of the outcome with the observation probabilities and the covariate are strong.     

Marginal homogeneity,symmetry, and independence

A contingency table of the mc form provides a convenient summary of data when c individuals in a matched set9 each belonging to a different one of c classifications, are identified as belonging to one of m categories, A study in which matched sets (c=3) of 1 case, 1 hospital control, and 1 neighborhood control are classified into one of m=4 occupational categories would be an example, Independence in the cxm tables for each of the matched sets implies symmetry in the summary mc table with consequent marginal homogeneity. Adaptation of the Mantel-Haenszel procedure for testing independence to the case of many cxm tables so as to yield a chi square with (cl)(ml) degrees of freedom (DF) provides a test of marginal homogeneity in the summary mc table. This can be viewed as a test of symmetry directed against alternatives which would make for marginal inhomogeneity and can differ     

陈子展先生与近代文学研究——试析他的两部近代文学史

本着重阐述陈子展先生在中国近代学研究方面的成就与贡献。陈子展先生对近代学的研究主要体现于他的两部作《中国近代学之变迁》《最近三十年中国学史》,在这两部作中,他提出了在前人研究基础上的属于他自己独立思考的见解,这些见解对1898年至1928年这30年间的近代学发展做了有价值的分析与总结。两部作被学术界公认为在中国近代学研究史上具有早期开创性意义,至今不失其学术价值。     

经学振荡式发展的原因及启示

我国古代的经学,由西汉今文经学到东汉古文经学,到魏晋“王学”,到南北朝隋唐疏注之学,到宋明义理之学,到乾嘉考据之学,经过了四次振荡式发展。造成经学振荡式发展的原因,主要有社会文化需求的阶段性变化、实现儒学社会价值与追求儒经学术品位的矛盾,以及经典文本特点（主要是文词的多义性和句义的可扩展性）这三点。经学振荡式发展规律告诉我们,二十一世纪的国学研究,必须贴近现实,面向社会,为大众服务。     

The declining influence of family background on educational attainment in Australia: The role of measured and unmeasured influences

The paper examines changes in the influence of family background, including socioeconomic and social background variables on educational attainment in Australia for cohorts born between 1890 and 1982. We test hypotheses from modernization theory on sibling data using random effects models and find: (i) substantial declines in the influence of family background on educational attainment (indicated by the sibling intraclass correlations); (ii) declines in the effects of both economic and cultural socioeconomic background variables; (iii) changes in the effects of some social background variables (e.g., family size); (iv) and declines in the extent that socioeconomic and social background factors account for variation in educational attainment. Unmeasured family background factors are more important, and proportionally increasingly so, for educational attainment than the measured socioeconomic and social background factors analyzed. Fixed effects models showed steeper declines in the effects of socioeconomic background variables than in standard analyses suggesting that unmeasured family factors associated with socioeconomic background obscure the full extent of the decline.     

日本“江户锁国论”质疑

“江户锁国论”在日本史学界流传已久 ,然而这种表述并不符合历史事实。江户幕府“锁国”的目标仅仅在于铲除危害其统治的天主教信仰。关于德川幕府的禁书政策是“锁国体制”下全面抵制西洋文化的重要一环的说法也是一种误解。历史事实是 ,在江户时代 ,除与天主教有关的汉译西书 4 8种之外 ,有关西方的书籍大量流入日本 ,从而促发了日本人学习西方近代科学和社会思想的兰学运动。江户时代 ,除抵制天主教之外 ,不但没有割断与世界的联系 ,而且吸收了大量的西方近代文化。“江户锁国论”的传统认识影响了人们对江户时代整体评价的客观性
