Slepian's inequality via the central limit theorem

We define a partial ordering of distributions which is preserved under convolutions and scale transformations. Some properties of this partial ordering are developed and then used to give a new argument for Slepian's inequality (1962).     

Iterated Partial Sum Sequences of Regression Residuals and Tests for Changepoints with Continuity Constraints

Iterated partial sum sequences of regression least squares residuals are defined and large sample properties of sequences of stochastic processes defined by these iterated partial sums are discussed. Also, finite sample properties of the iterated partial sum sequences are obtained. These include a property of least squares residuals of polynomial fits to equispaced data, namely the iterated partial sums sum to 0 provided that the order of iteration is not greater than the order of the polynomial, thus extending the well-known result that residuals sum to 0. Iterated partial sums are shown to play an important role in testing regression parameters for changes at unknown times under the constraint of continuity.

血糖近红外光谱分析中两种常用化学计量学方法的比较

采用主成分回归和偏最小二乘法分别对血糖近红外光谱进行分析,建立数学校正模型。主成分回归模型的相关系数为 0 9294,偏最小二乘法模型相关系数为 0 9998。对两种方法进行比较,确定对血糖近红外光谱分析的方法。     

Sampling with partial enumeration from bivariate populations

In multi-character surveys, determination of sample sizes for studying various characters poses a difficult problem. In some situations, instead of observing the same units for all the characters it may be desirable to have some units observed for all the characters whereas some extra units for each character are observed separately. Such type of sampling has been defined here as sampling with partial enumeration. In the present investigation the efficiency of sampling with partial enumeration has been examined as compared to the usual two phase sampling for the study of only two characters.     

物价变动对传统会计的冲击及会计对策

传统会计是以币值稳定为基础的,物价变动给传统会计带来了一个普遍性的信息失真问题。在物价变动时期,传统会计计量的资产和收益难以反映其实际情况,会计信息的可理解性减弱,企业的再生产能力也会受到损害。局部改革法从某一局部改善会计信息的质量,全面改革法从根本上物价变动引起的会计问题。     

并购市场局部均衡分析和定价模式探讨

运用局部均衡分析方法,分析了并购市场特殊的供求曲线、局部均衡以及在完全信息和不完全信息两种条件下的封闭拍卖并购定价模型.目的在于考察并购市场的运行机制,以便保证并购的高效运行,充分发挥市场机制在配置存量资源方面的优势作用.     

刑事二审“全面审查原则”的理性反思

设立审判程序的目的不仅仅在于发现案件真相,更在于对发生在控辩双方之 间的争端做出一个权威的结论。二审程序存在的合理根据在于为控辩双方再次提供法律救济 的机会。如果二审法院可以无视诉争的范围,而机械地进行貌似公允的全面审查,不仅有悖司 法审判权运作的基本规律和诉讼程序的安定性,最终也将造成诉讼拖延和诉讼效率的下降。 二审法院的审查范围一般应限制在争端双方上诉或抗诉的理由上。     

贵生论

贵生即贵生贱物、重生轻物 ,也就是把自己分为“生”(自己的生命 )和“物”(自己生命之外的东西 ) ,认为自己的生命贵于自己生命之外的东西 ,生命是自己最宝贵最有价值的东西。一个人如果贵生轻物 ,那么即使他失去身外名货 ,得到的却是最宝贵最有价值的东西 :健康长寿 ;反之 ,如果他重物轻生 ,那么即使他得到了身外名货 ,却失去了性命 ,岂非杀身以易衣、断首以易冠 ?所以 ,贵生是善待自己的根本原则     

Estimation and testing in generalized partial linear models—A comparative study

A particular semiparametric model of interest is the generalized partial linear model (GPLM) which extends the generalized linear model (GLM) by a nonparametric component.The paper reviews different estimation procedures based on kernel methods as well as test procedures on the correct specification of this model (vs. a parametric generalized linear model). Simulations and an application to a data set on East–West German migration illustrate similarities and dissimilarities of the estimators and test statistics.
