Conditional variance estimation in heteroscedastic regression models

First, we propose a new method for estimating the conditional variance in heteroscedasticity regression models. For heavy tailed innovations, this method is in general more efficient than either of the local linear and local likelihood estimators. Secondly, we apply a variance reduction technique to improve the inference for the conditional variance. The proposed methods are investigated through their asymptotic distributions and numerical performances.     

Partitioning k multivariate normal populations according to equivalence with respect to a standard vector

We propose optimal procedures to achieve the goal of partitioning k multivariate normal populations into two disjoint subsets with respect to a given standard vector. Definition of good or bad multivariate normal populations is given according to their Mahalanobis distances to a known standard vector as being small or large. Partitioning k multivariate normal populations is reduced to partitioning k non-central Chi-square or non-central F distributions with respect to the corresponding non-centrality parameters depending on whether the covariance matrices are known or unknown. The minimum required sample size for each population is determined to ensure that the probability of correct decision attains a certain level. An example is given to illustrate our procedures.     

Design of a CSP-1 plan based on regret-balanced criterion

This article explores the problem of designing a CSP-1 plan with the specified average outgoing quality limit (AOQL), the acceptable quality level (AQL), and the limiting quality level (LQL) value. By adopting the regret-balanced criterion under the producer's and consumer's interests of quality, we can design the optimal CSP-1 plan.     

A unified approach to regression analysis under double-sampling designs

We propose a unified approach to the estimation of regression parameters under double-sampling designs, in which a primary sample consisting of data on the rough or proxy measures for the response and/or explanatory variables as well as a validation subsample consisting of data on the exact measurements are available. We assume that the validation sample is a simple random subsample from the primary sample. Our proposal utilizes a specific parametric model to extract the partial information contained in the primary sample. The resulting estimator is consistent even if such a model is misspecified, and it achieves higher asymptotic efficiency than the estimator based only on the validation data. Specific cases are discussed to illustrate the application of the estimator proposed.     

积极进取勇于创新 ——邓小平理论"三进"的教学实践

邓小平理论"进教材、进课堂、进头脑"是高校政治理论课的重要使命.目前,邓小平理论"进教材"、"进课堂"均已做到,但"进头脑"仍是政治理论课教师面临的重要课题.我院在邓小平理论"三进"教学实践中积累了一些经验、取得了一些成绩.     

雷锋生命价值的三重维度及当代意蕴

雷锋的生命价值从历史、空间、境界三重维度上表现为延伸性、普遍性和超越性。雷锋的生命价值符合人与社会全面发展进步的需要,即符合人的超越性的要求、符合群体共同发展的要求、符合中华民族道德实践的要求、符合中国共产党的宗旨要求,是对生命为什么有价值、生命价值是什么、怎样实现生命价值问题的直接解答。     

地方政府权力清单制度法治化研究

地方政府权力清单制度的法治化是通过法律规范地方各级政府及其部门的权力以清单的形式详细清晰地予以公布,并产生强制性的约束力,规范政府的权力边界,要求政府必须按照清单所列权力依法行政,不允许越权执法,旨在制约行政权力,保障公民权利。本文基于行政法定原则、行政公开原则、行政便民原则阐释了地方政府权力清单制度法治化的理论基础,然而,地方政府权力清单制度的实践中仍存在一些问题,应当从权力类型的科学化管理和权力清单范围全覆盖等方面优化权力清单的内容,从权力清单制定主体、权力行使的程序和清单制度的实施方式等方面提供程序性的保障,从权力清单的责任约束和有效监督方面建立刚性制约机制,以此来完善地方政府权力清单制度的法治化,防止行政权力的滥用,推进法治政府的建设。

麦尔维尔与尼采的“精神相遇”

美国作家麦尔维尔与德国哲学家尼采处于不同的时空与国度,二人的生命没有有形的交集。但是,二人在生活际遇、诗哲气质、艺术追求以及哲学思考上有诸多的共振点,这使得二人的思想穿越时空,产生了心灵共振和精神相遇。麦尔维尔在19世纪50年代的小说创作无意识地成为了尼采酒神精神的文学再现。     

转型期民事纠纷的可诉范围研究——以诉的利益为视角

民事纠纷如果需要通过诉讼方式解决,必须具备"可诉性"或"可司法性",即具备由诉讼来解决纠纷所需要的条件或特征.关于纠纷的可诉性问题,我国<民事诉讼法>的规定是模糊、不确定的.本文分析了现行法律规定下,纠纷可诉性范围存在的问题,引申出"诉的利益"的概念.诉的利益是我国诉讼法上所没有的概念,通过对诉的利益的分析,纠纷的可诉性可以得到合理的界定.此外,还对诉的利益的制度保障提出了对策和思路,并建议完善诉讼外的纠纷替代性解决机制.
