On influence diagnostic in univariate elliptical linear regression models

We discuss in this paper the assessment of local influence in univariate elliptical linear regression models. This class includes all symmetric continuous distributions, such as normal, Student-t, Pearson VII, exponential power and logistic, among others. We derive the appropriate matrices for assessing the local influence on the parameter estimates and on predictions by considering as influence measures the likelihood displacement and a distance based on the Pearson residual. Two examples with real data are given for illustration.     

从诗“味”看崔滋对诗歌审美特征的认识

在朝鲜诗学发展史上,崔滋以朝鲜诗歌作为批评和研究对象,对诗歌诸多方面进行了广泛的探讨,其中对诗歌的审美特征"味"给予了充分的关注.这主要表现在三个方面一、提出了重要命题"有味不如意尽";二、提出了"象外之气"说;三、注重诗歌"味"的整体性.

Non-parametric Estimation of the Residual Distribution

Consider a heteroscedastic regression model Y = m ( X ) +σ( X )ε, where the functions m and σ are "smooth", and ε is independent of X . An estimator of the distribution of ε based on non-parametric regression residuals is proposed and its weak convergence is obtained. Applications to prediction intervals and goodness-of-fit tests are discussed.     

On cumulative entropies

In analogy with the cumulative residual entropy recently proposed by Wang et al. [2003a. A new and robust information theoretic measure and its application to image alignment. In: Information Processing in Medical Imaging. Lecture Notes in Computer Science, vol. 2732, Springer, Heidelberg, pp. 388–400; 2003b. Cumulative residual entropy, a new measure of information and its application to image alignment. In: Proceedings on the Ninth IEEE International Conference on Computer Vision (ICCV’03), vol. 1, IEEE Computer Society Press, Silver Spring, MD, pp. 548–553], we introduce and study the cumulative entropy, which is a new measure of information alternative to the classical differential entropy. We show that the cumulative entropy of a random lifetime X can be expressed as the expectation of its mean inactivity time evaluated at X. Hence, our measure is particularly suitable to describe the information in problems related to ageing properties of reliability theory based on the past and on the inactivity times. Our results include various bounds to the cumulative entropy, its connection to the proportional reversed hazards model, and the study of its dynamic version that is shown to be increasing if the mean inactivity time is increasing. The empirical cumulative entropy is finally proposed to estimate the new information measure.     

“中国情趣”、中国旅行与东方主义——《谷崎润一郎与东方主义》述评

《谷崎润一郎与东方主义》的作者,独出心裁地将赛义德针对西方的东方主义理论应用于日本,并以谷崎润一郎为例具体分析了日本大正时代的东方主义话语。该书有三个特色:1.不仅指出了谷崎的东方主义话语,而且还明确了他的“西方主义”和自我东方主义的倾向。2.以“中国情趣”为突破口,来探讨谷崎与中国文学、文化的关系以及他的中国观。3.详细考察了谷崎的两次中国之旅及与中国作家的交流,并分析了中国旅行对他创作的影响。该书在中国的翻译与出版,对中国读者全面理解谷崎润一郎有较大的参考价值。     

振叶寻根 直指词心——评《倦驼庵稼轩词说》

顾随《倦驼庵稼轩词说》是一部很重要的研究稼轩词的论著。这是作者自己词作创作经验和宋词鉴赏方法的结晶。作者从三个方面展开论述,一是重点分析了《稼轩词》主旨美:"诚"和"高致"。这个"诚"就是辛弃疾发自内心的爱国热情和生命热望;"高致"则是作者心胸精神的自然流露。二是分析稼轩词艺术美:灵动妙悟,注重词汇、句式和词义之间的圆融和谐。三是他为读者欣赏阅读稼轩词指出方法:尚友词人,了解词人文化背景。
