On a modified test of equality of scale parameters of exponential distributions

In this paper, an exact distribution of a modifier likelihood ratio criterion for testing the equality of scale parameters of several two parameter exponential distributions is obtained for the case of unequal sample size in a computational form. A short table of critical values of the proposed statistic is also presented.     

向徐特立学习,明“八荣八耻”,做新时代的模范

荣辱观念具有民族的继承性,更具有明显的时代性。中华民族的荣辱观经过数十年极左思潮的冲击和市场经济大潮的影响,原本泾渭分明的传统荣辱观逐渐变得模糊起来。徐特立的崇高品德,是我国民族优秀文化丰富积淀的写照,至今仍旧发射出夺目的光彩。他为广大国民树立胡锦涛同志提出"的八荣八耻"的荣辱观提供了很好的榜样。以徐特立为榜样,"明八荣八耻",对于广大公务员、教师和青年学生尤其具有切合现实的意义。     

Heteroskedasticity-consistent covariance matrix estimation:white's estimator and the bootstrap ∗

This paper considers the issue of estimating the covariance matrix of ordinary least squares estimates in a linear regression model when heteroskedasticity is suspected. We perform Monte Carlo simulation on the White estimator, which is commonly used in.

empirical research, and also on some alternatives based on different bootstrapping schemes. Our results reveal that the White estimator can be considerably biased when the sample size is not very large, that bias correction via bootstrap does not work well, and that the weighted bootstrap estimators tend to display smaller biases than the White estimator and its variants, under both homoskedasticity and heteroskedasticity. Our results also reveal that the presence of (potentially) influential observations in the design matrix plays an important role in the finite-sample performance of the heteroskedasticity-consistent estimators.     

论毛泽东的军事法思想

毛泽东军事法思想是毛泽东思想的重要组成部分,散见于毛泽东关于军队的组织体系、纪律条令以及作战原则、战犯审判等方面的论述。毛泽东关于军事组织法的核心思想是党对军队的绝对领导,为贯彻这一指导思想,毛泽东极为重视军队政治工作,将其作为"我军的生命线",同时强调军事指挥权的集中。毛泽东对军事行政法和军事刑法的主要贡献是确立"三大纪律八项注意",并在实践中严惩违反军纪的行为;对于历史上有军功的人员,主张功过不能折抵。毛泽东在战争法则上的主要思想是自卫原则和优待战俘原则,同时认为战俘与战犯有区别,主张严惩国内外战犯。毛泽东的军事法思想深刻影响了我国的军事法制建设,丰富了国际军事法的相关内容。     

Nonparametric estimation of the sojourn time distributions for a multipath model

Summary. We use a multipath (multistate) model to describe data with multiple end points. Statistical inference based on the intermediate end point is challenging because of the problems of nonidentifiability and dependent censoring. We study nonparametric estimation for the path probability and the sojourn time distributions between the states. The methodology proposed can be applied to analyse cure models which account for the competing risk of death. Asymptotic properties of the estimators proposed are derived. Simulation shows that the methods proposed have good finite sample performance. The methodology is applied to two data sets.

高校道德建设的"基础工程":社会公德教育

由于大学生群体中存在着道德滑坡现象,又由于大学生群体具有特殊的示范、辐射作用,对大学生的社会公德教育已成为高校道德建设的"基本工程".此项"基本工程"必须把握两个极为重要的基点在日常习惯、生活方式习惯、人际习惯、自律习惯,努力培养良好的日常生活道德习惯,使习惯成为自然;在文明宿舍(食堂、教室、班级……)等创建活动、荣誉考试制度(无人监考)尝试、校风校园环境建设等方面,开拓丰富多样的道德实践活动,使知与行相融协调.     

邓小平"两点论"思想探析

邓小平在设计我国社会主义建设的宏伟蓝图和指导我国革命与建设实践时 ,始终把“两点论”作为基本的方法论原则。邓小平的“两点论”思想 ,是他根据和平与发展的时代主题 ,根据科技进步和改革开放的时代特征 ,对马克思主义对立统一思想所作的创造性发展
