Three Approximate Solutions to the Multivariate Behrens–Fisher Problem

ABSTRACT

This article provides three approximate solutions to the multivariate Behrens–Fisher problem: the F statistic, the Bartlett, as well as the modified Bartlett corrected statistics. Empirical results indicate that the F statistic outperforms the other two and five existing procedures. The modified Bartlett corrected statistic is also very competitive.     

Multiple Comparisons Among Mean Vectors When the Dimension is Larger Than the Total Sample Size

We consider pairwise multiple comparisons and multiple comparisons with a control among mean vectors for high-dimensional data under the multivariate normality. For such cases, the statistics based on the Dempster trace criterion are given, and also their approximate upper percentiles are derived by using the Bonferroni’s inequality. Finally, the accuracy of their approximate values is evaluated by Monte Carlo simulation.     

吸收犯初探

吸收犯是一个争议颇多的概念,其与牵连犯、连续犯之间存在着错综复杂的关系。准确描述吸收犯与牵连犯等相关概念之间的关系并重新进行理论架构已经成为当务之急。有鉴于此,本文从分析吸收犯的内涵入手,围绕着“吸收犯与牵连犯的关系”这一关键性命题进行论证,最终形成了以吸收犯取代牵连犯的设计方案。     

平方数的位数和函数的渐近分布

设正整数n的二进制展开式为n=∑εi2^i,这里εi=0或1,i≥0,定义二进制位数和函数为s（n）=∑εi.证明了假设n^2的二进制展开式中每个位置上0和1出现的概率相等,则s（n^2）在模2和模3的剩余类里的浙近分布是均匀的．     

实行过限研究

实行过限是共同犯罪中一类独特的错误形态,当属刑法中错误论的范畴;实行过限问题关系到共同犯罪的认定及共犯的成立范围。在实行过限的场合,部分行为人完全有可能就过限行为成立新的共犯关系,有必要就前后两种不同的共犯之间的罪数问题作深入分析,并以此确认各行为人的刑事责任。     

电子银行市场扩容的竞合机制研究

本文详细分析了电子银行市场的技术经济特性与需求特性,认为电子银行市场存在自然垄断特性,即成本的劣可加性,此类市场的可维持性要求市场竞争主体间竞合机制的建立。文中建立了一个市场扩容的竞合机制,对竞合机制的外部规制进行了深入讨论,并提出了相关的政策性建议。     

银行资本扩张的路径选择——以连云港东方农商银行为例

结合连云港东方农商银行的运营实践,阐述了资本扩张与股份制改造的必要性,在此基础上提出转换股本、走彻底的股份制之路的建议,认为增资扩股、扩大控股能力、引进战略投资、实现双赢合作是连云港农商银行资本扩张的路径选择。     

家族企业社会责任的选择性参与

基于利益相关者理论视角,利用3 759家全国私营企业样本,区分内外部利益相关者,探究家族企业在承担内外部社会责任上的行为表现及不同发展阶段承担内外部社会责任的行为模式,结果表明:（1）家族涉入会提高企业外部慈善捐赠投入,但会抑制企业内部员工福利投入。（2）相比成熟期企业,新创企业家族涉入与外部慈善捐赠的正向关系更强,而与员工福利投入的负向关系没有改变。（3）企业家的人力资本越强,家族涉入与员工福利投入的负向关系越会减弱。在对样本选择、替代变量等问题进行稳健性检验后,结果保持稳定。研究揭示家族企业在承担内外部社会责任时遵循不同的行为逻辑,并且,优先遵循“惠外”的行为模式。     

Karhunen–Loeve expansion for the additive two-sided Brownian motion

In the paper, Karhunen–Loeve expansion and Pythagorean-type distribution identities for the additive two-sided Brownian motion are derived. As the applications of Karhunen–Loeve expansion, the corresponding Laplace transform and small ball probability for the L₂ norm are presented.     

Moment convergence of powered normal extremes

In this article, convergence for moments of powered normal extremes is considered under an optimal choice of normalizing constants. It is shown that the rates of convergence for normalized powered normal extremes depend on the power index. However, the dependence disappears for higher-order expansions of moments.
