Bootstrap method in ranking and slippage problems

In this paper, the bootstrap method of Efron (1979) is given for a ranking and a slippage problem, where the ranking (or slippage) is with respect to the mean of the distributions. The method is also applied to obtain a confidence interval for the largest mean.     

Bayesian Proportional Hazard Analysis of the Timing of High School Dropout Decisions

In this paper, I study the timing of high school dropout decisions using data from High School and Beyond. I propose a Bayesian proportional hazard analysis framework that takes into account the specification of piecewise constant baseline hazard, the time-varying covariate of dropout eligibility, and individual, school, and state level random effects in the dropout hazard. I find that students who have reached their state compulsory school attendance ages are more likely to drop out of high school than those who have not reached compulsory school attendance ages. Regarding the school quality effects, a student is more likely to drop out of high school if the school she attends is associated with a higher pupil–teacher ratio or lower district expenditure per pupil. An interesting finding of the paper that comes along with the empirical results is that failure to account for the time-varying heterogeneity in the hazard, in this application, results in upward biases in the duration dependence estimates. Moreover, these upward biases are comparable in magnitude to the well-known downward biases in the duration dependence estimates when the modeling of the time-invariant heterogeneity in the hazard is absent.     

On the efficiency of two-stage and three-stage least squares estimators

This paper utilizes the results of Kruskal (1968), Zyskind (1967), and more recently Milliken and Albohali (1984) to derive a simple necessary and sufficient condition for 3SLS to be equivalent to 2SLS. This condition depends upon the inverse of the variance:covariance matrix of the disturbances, and the set of second stage regressors of each structural equation. More importantly, this condition should prove useful for econometric students and provides an easy method for checking sufficiency.     

TESTS FOR EXPONENTIALITY AGAINST GAMMA ALTERNATIVES USING NORMALIZED WAITING TIMES

In this article, we present some tests for Exponentiality against Gamma alternatives by using normalized waiting times. The test is constructed by using a quadratic form. The asymptotic distribution of the proposed test is derived. The power of the test is computed through Monte Carlo simulation and is compared with Linhart (1965) test, Bain and Engelhardt (1975) test and Keating et al. (1990) test.     

The power functions of the likelihood ratio tests for a simply ordered trend in normal means

Likelihood ratio tests for the homogeneity of k normal means with the alternative restricted by an increasing trend are considered as well as the likelihood ratio tests of the null hypothesis that the means satisfy the trend. While the work is primarily a survey of results concerning the power functions of these tests, the extensions of some results to the case of not necessarily equal sample sizes are presented. For the case of known or unknown population variances, exact expressions are given for the power functions for k=3,4, and approximations are discussed for larger k. The topics of consistency, bias and monotonicity of the power functions are included. Also, Bartholomew's conjectures concerning minimal and maximal powers are investigated, with results of a new numerical study given.     

Measuring non-linear dependence for two random variables distributed along a curve

We propose new dependence measures for two real random variables not necessarily linearly related. Covariance and linear correlation are expressed in terms of principal components and are generalized for variables distributed along a curve. Properties of these measures are discussed. The new measures are estimated using principal curves and are computed for simulated and real data sets. Finally, we present several statistical applications for the new dependence measures.     

《吕氏春秋》之于名家评析

《吕氏春秋》是一部综合诸子百家学说而成的著作,在中国文化发展史上具有重要地位和作用。名家学说在《吕氏春秋》中占有一定的地位。《吕氏春秋》之于名家的意义体现在两方面：一是保存了先秦名家的部分相关资料;二是可以启发学术界对中国思辩哲学相对落后之原因等深层问题的思考。     

试论离婚之精神损害赔偿制度

离婚之精神损害有离因精神损害和离婚精神损害两种.前者是夫妻一方对另一方构成侵权行为而导致离婚,从而给一方造成精神痛苦,受害方可请求精神损害赔偿.我国新的<婚姻法>确立了这一精神损害赔偿制度,填补了我国婚姻制度的一个空缺.而后者是夫妻一方对另一方并无侵权行为,离婚本身即为构成精神损害之直接原因,如由于第三者插足、婚外恋、夫妻一方被判处徒刑等.这种离婚同样使一方受到精神损害,自然也应得精神损害赔偿.遗憾的是,新的<婚姻法>并未作此规定.因此,要完善我国离婚之精神损害赔偿制度,不仅要使离婚之精神损失赔偿的权利义务主体进一步扩大,把第三者也作为离婚之精神损害赔偿的义务主体,而且还要将离因精神损害赔偿扩大到离婚精神损害赔偿,将因婚外恋、第三者插足、因配偶一方犯罪而被判入狱和其他原因导致离婚的情况作出规定,使精神受害者得到应有的经济救济和补偿.     

论中国共产党建党理论的创新

实践证明,党的建设是我们党克敌制胜的一大法宝,而建党理论的创新是前提。中国共产党把马克思列宁主义建党理论同中国实际相结合,提出适合中国国情的党的建设理论,反映了时代的需要,全面体现了党的先进性,增强了党的凝聚力和战斗力。学习掌握这些经验,对于我们坚持新时期党的建设纲领有着重要意义。
