Divergence-based estimation and testing with misclassified data

The well-known chi-squared goodness-of-fit test for a multinomial distribution is generally biased when the observations are subject to misclassification. In Pardo and Zografos (2000) the problem was considered using a double sampling scheme and ø-divergence test statistics. A new problem appears if the null hypothesis is not simple because it is necessary to give estimators for the unknown parameters. In this paper the minimum ø-divergence estimators are considered and some of their properties are established. The proposed ø-divergence test statistics are obtained by calculating ø-divergences between probability density functions and by replacing parameters by their minimum ø-divergence estimators in the derived expressions. Asymptotic distributions of the new test statistics are also obtained. The testing procedure is illustrated with an example.

Generalized additive models for location, scale and shape

Summary.  A general class of statistical models for a univariate response variable is presented which we call the generalized additive model for location, scale and shape (GAMLSS). The model assumes independent observations of the response variable y given the parameters, the explanatory variables and the values of the random effects. The distribution for the response variable in the GAMLSS can be selected from a very general family of distributions including highly skew or kurtotic continuous and discrete distributions. The systematic part of the model is expanded to allow modelling not only of the mean (or location) but also of the other parameters of the distribution of y , as parametric and/or additive nonparametric (smooth) functions of explanatory variables and/or random-effects terms. Maximum (penalized) likelihood estimation is used to fit the (non)parametric models. A Newton–Raphson or Fisher scoring algorithm is used to maximize the (penalized) likelihood. The additive terms in the model are fitted by using a backfitting algorithm. Censored data are easily incorporated into the framework. Five data sets from different fields of application are analysed to emphasize the generality of the GAMLSS class of models.     

Proportional reversed hazard rate model and its applications

The purpose of this paper is to study the structure and properties of the proportional reversed hazard rate model (PRHRM) in contrast to the celebrated proportional hazard model (PHM). The monotonicity of the hazard rate and the reversed hazard rate of the model is investigated. Some criteria of aging are presented and the inheritance of the aging notions (of the base distribution) by the PRHRM is studied. Characterizations of the model involving Fisher information are presented and the statistical inference of the parameters is discussed. Finally, it is shown that several members of the proportional reversed hazard rate class have been found to be useful and flexible in real data analysis.     

合作学习与课堂参与性——通过合作学习促进英语课堂学生参与性的实验研究

鉴于英语教学重心向语言输出和运用能力的转移,学生在课堂上不再是被动的接受者.富兰克林说(1706-1790):告诉我,我会忘记;教给我,我可能记住;让我参与,我才能学会.因此,怎样让学生成为课堂的主体和积极的参与者成为教师关注的话题.本文通过实证研究调查了利用合作学习法提高英语课堂学生参与性的可能性和可行性,对比分析了实验班和控制班课堂参与状况,并对合作学习的实施提出了建设性的建议.

小型制造业信息化发展模式的研究

该文简述了世界制造业面临的挑战及其信息系统的发展 ,提出了我国小型制造业信息化的目的 ,并分析了小型制造业信息化面临的困难。最后提出了小型制造业信息化的群落合作发展模式。在这种模式中 ,一个企业群落应建立包括群落层和企业层的两层式信息系统。为实现群落合作发展模式 ,在每个小型制造业的群落里 ,应建立一个从事信息系统开发和进行信息服务的IT性质的企业实体来实施群落两层信息系统的建设和运行 ,这个IT性质的企业与信息系统共生存 ,为群落中的企业提供全天候的信息服务 ,特别是在条件成熟时为各个企业的信息系统添加新的功能。     

盛衰皆因儒——元杂剧命运的一种解读

元杂剧在经历了短暂的繁盛之后悄然衰微,其繁盛有着文人儒士的参与之功.元初封建宗法制度的失承及儒家思想的失落形成了相对的自由环境,而其后理学的复归和统治体系的确立,反向构成元杂剧发展的桎梏.儒生及儒家思想的沉浮,对文学艺术发展的影响永远是一个复杂而值得探讨的问题.
