A modification of watson's statistic for goodness-of-fit

A modification of Watson's statistic is suggested for dealing with stochastically ordered alternatives in the goodness-of-fit setting.     

Robust methods of estimation of regression coefficients 1

Recently, cumulative residual entropy (CRE) has been found to be a new measure of information that parallels Shannon's entropy (see Rao et al. [Cumulative residual entropy: A new measure of information, IEEE Trans. Inform. Theory. 50(6) (2004), pp. 1220–1228] and Asadi and Zohrevand [On the dynamic cumulative residual entropy, J. Stat. Plann. Inference 137 (2007), pp. 1931–1941]). Motivated by this finding, in this paper, we introduce a generalized measure of it, namely cumulative residual Renyi's entropy, and study its properties. We also examine it in relation to some applied problems such as weighted and equilibrium models. Finally, we extend this measure into the bivariate set-up and prove certain characterizing relationships to identify different bivariate lifetime models.     

On the asymptotic distribution of Cook's distance in logistic regression models

It sometimes occurs that one or more components of the data exert a disproportionate influence on the model estimation. We need a reliable tool for identifying such troublesome cases in order to decide either eliminate from the sample, when the data collect was badly realized, or otherwise take care on the use of the model because the results could be affected by such components. Since a measure for detecting influential cases in linear regression setting was proposed by Cook [Detection of influential observations in linear regression, Technometrics 19 (1977), pp. 15–18.], apart from the same measure for other models, several new measures have been suggested as single-case diagnostics. For most of them some cutoff values have been recommended (see [D.A. Belsley, E. Kuh, and R.E. Welsch, Regression Diagnostics: Identifying Influential Data and Sources of Collinearity, 2nd ed., John Wiley & Sons, New York, Chichester, Brisban, (2004).], for instance), however the lack of a quantile type cutoff for Cook's statistics has induced the analyst to deal only with index plots as worthy diagnostic tools. Focussed on logistic regression, the aim of this paper is to provide the asymptotic distribution of Cook's distance in order to look for a meaningful cutoff point for detecting influential and leverage observations.

伊斯兰教“圣容”描述小识

大家都熟知伊斯兰教禁止偶像崇拜,但伊斯兰教是否允许用文字对圣人的形象进行描述,有的学者对此并无明晰的认识。从圣训、《天方至圣实录》等中外伊斯兰教典籍,以及碑刻、宣传单等资料看,用文字描述圣容的做法,与伊斯兰教禁止偶像崇拜并不相违。在中国,用文字描述圣容的做法也已经延续了相当长的时间。     

《临川四梦》的地方特色与赣东民间演剧的关系

《临川四梦》旦、生用韵基本规范,但净、丑、贴、末等次要角色的戏剧场面活泼鄙俗,多用方言俗语,体现出浓重的赣东民间风情和演剧特色。这种现象在同时代的昆腔传奇曲家中是不可能有的,这是汤显祖＂临川四梦＂最鲜明的特色。     

Des corps étrange(r)s dans la police ? Les policiers minoritaires à Paris et à Berlin

Fieldwork in police stations in the Parisian region and Berlin is used to comparatively analyze how the assignment of identities shapes the occupational experiences of police officers recruited from among visible minorities. The processes for constructing and deconstructing the positions of minorities take place through negotiations during interactions among colleagues. They also depend on the institutional context. The stance of “denial” adopted by the French staff opens the way to tensions between officers from visible minorities and the others, whereas interventions by superiors in Berlin reduce the room for conflict while assigning a cultural identity to police officers recruited “from immigration”.     

中国知识型失业基本原因分析

当下中国知识型失业凸显了体制转型的失谐,其成因套用西方就业理论解释显得捉襟见肘;而仅仅归因于政府社会保障、就业服务等制度缺失或归因于高等教育、社会中介、社会观念等因素也显得差强人意,它们虽重要但非主要.影响中国知识型失业的主要的变量,一是劳动用工制度或就业市场体制;二是工业化战略中的产业结构和产业链因素.前者属于"生产...     

随笔的理趣魅力浅析——读张吉刚随笔集《别做聪明的傻瓜》

随笔原本是作为人类自由思想的载体而出现的一种文体,故随笔的第一特质是说理,即表达思想与见解;启迪智慧是随笔的核心价值所在。从这个角度来看,张吉刚随笔集《别做聪明的傻瓜》充分体现了随笔的理趣魅力。     

The marginalisation of children by the legal process

A major study carried out in the Melbourne Children's Court, Victoria, Australia, during 1993–1995, of the factors that influence magistrates' decision-making in child abuse cases, found that magistrates relied more on their legal training and individual discretion than on information from the child protection service when making these decisions. Magistrates' emphasis on adversarial procedures meant that the need to establish the facts in a case was the court's primary consideration and that children's interests, and welfare concerns about them, were marginalised in the hearing of child abuse matters. The article reports on this aspect of the larger study: how the adversarial process ill serves the rights, and best interests, of children in the hearing of child abuse matters and provides case examples to illustrate this. The information is drawn from the qualitative and quantitative data gathered for the major study; data collected from the observation of court hearings, interviews with magistrates and court record analysis.
