Combining Unbiased Ridge and Principal Component Regression Estimators

In the presence of multicollinearity problem, ordinary least squares (OLS) estimation is inadequate. To circumvent this problem, two well-known estimation procedures often suggested are the unbiased ridge regression (URR) estimator given by Crouse et al. (rid="CIT0004" data-refLink="_i58" href="#">1995 Crouse , R. , Jin , C. , Hanumara , R. ( 1995 ). Unbiased ridge estimation with prior information and ridge trace . Commun. Statist. Theor.

In this article, we proposed a new class of estimators, namely modified (r, k) class ridge regression (MCRR) which includes the OLS, the URR, the (r, k) class, and the principal components regression (PCR) estimators. It is based on a criterion that combines the ideas underlying the URR and the PCR estimators. The standard properties of this new class estimator have been investigated and a numerical illustration is done. The conditions under which the MCRR estimator is better than the other two estimators have been investigated.

重庆话的儿尾

在前人研究的基础上进一步探讨了重庆话儿尾的文白音值和重庆话儿尾在语素“儿”的发展演变中所处的特殊地位 ,即重庆话儿尾正处于“儿”从实语素到虚语素发展的承接阶段上     

间接经济效益的波及效应和摄动效应分析

直接经济效益和经济效益传递系数两个变量的变动都会引起国民经济间接经济效益总 量的变动, 前者称为波及效应, 后者称为摄动效应. 本文对这两种效应进行了深入分析和探讨, 并利用投入产出表提供的数据, 分析了1987- 1997 年四川省国民经济的波及效应和摄动效 应. 提出了一种波及效应定位图的方法, 对各部门的波及效应进行了分类. 分析发现: 在10 年 中的不同时期, 促进国民经济间接经济效益总量增长的主要因素是不同的, 在前期是摄动效 应, 在中期是波及效应, 在后期是摄动效应和波及效应共同作用的结果     

向量随机波动模型的共因子研究

提出了向量随机波动模型波动协同持续(common persistence in vo lat ility) 的定义, 证明 了波动协同持续与协整(co in tegrat ion) 两者之间的等价关系; 同时, 基于Stock2W at son 与 Gonzalo2Granger 因子分解, 给出了协同持续因子(common persisten t facto r) 的两种不同的表 达形式, 证明了两者间存在着协整关系. 文中讨论了在隐因子过程为VAR (1) 的假定下, 协同 持续因子的表达以及协同持续因子存在的必要条件     

儿化在口语中注意的几个问题

儿化是语流音变中的一种,它在口语中往住会影响语言的语义、语法及修辞色彩,无论是在日常的口语交际,还是特殊的口语交际中都有儿化的出现。所以我们应注意儿化在口语中的读音和运用。     

Testing conditional independence via integrating-up transform

The main purpose of this paper is to test the conditional independence of two random vectors Y and Z given another random vector X. A new test statistic is developed relying on the Cramér–von Mises distance between two unconditional moments transformed from the conditional distributions, say ript>rc="/na101/home/literatum/publisher/tandf/journals/content/gsta20/2018/gsta20.v052.i04/02331888.2018.1473400/20180713/images/gsta_a_1473400_ilm0001.gif" alt=" />ript>rc="//:0" alt=" class="mml-formula" data-formula-source="{"type" : "image", "src" : "/na101/home/literatum/publisher/tandf/journals/content/gsta20/2018/gsta20.v052.i04/02331888.2018.1473400/20180713/images/gsta_a_1473400_ilm0001.gif"}" />rc="//:0" alt=" data-formula-source="{"type" : "mathjax"}" />roll" altimg="eq-00001.gif">F(y∣x) and ript>rc="/na101/home/literatum/publisher/tandf/journals/content/gsta20/2018/gsta20.v052.i04/02331888.2018.1473400/20180713/images/gsta_a_1473400_ilm0002.gif" alt=" />ript>rc="//:0" alt=" class="mml-formula" data-formula-source="{"type" : "image", "src" : "/na101/home/literatum/publisher/tandf/journals/content/gsta20/2018/gsta20.v052.i04/02331888.2018.1473400/20180713/images/gsta_a_1473400_ilm0002.gif"}" />rc="//:0" alt=" data-formula-source="{"type" : "mathjax"}" />roll" altimg="eq-00002.gif">F(y∣x,z), through ‘integrating up’.

Since the test statistic has a non-standard limiting distribution, a bootstrap procedure is also constructed to the calculation of critical values. Simulation studies indicate that the proposed testing procedure performs quite well and is very competitive comparing to the existing methods in terms of both size and power.     

中国加入WTO及其司法审查制度的完善

通过分析WTO有关协议和比较中国有关法律,从总体上讲,虽然中国司法审查制度在立法和受案范围等方面还有待完善,但是在司法审查的主体、对象和程序以及司法审查的独立性等方面与WTO的要求是一致的。在司法审查制度的完善问题上,应强调发展中国家的法律概念,允许中国有一个过渡期;同时,从长计议,建议尽早从立法上填补和完善司法审查的程序和范围,尤其是将抽象行政行为纳入到法院的司法审查之列。
