Robust pairwise multiple comparisons under short-tailed symmetric distributions

In one-way ANOVA, most of the pairwise multiple comparison procedures depend on normality assumption of errors. In practice, errors have non-normal distributions so frequently. Therefore, it is very important to develop robust estimators of location and the associated variance under non-normality. In this paper, we consider the estimation of one-way ANOVA model parameters to make pairwise multiple comparisons under short-tailed symmetric (STS) distribution. The classical least squares method is neither efficient nor robust and maximum likelihood estimation technique is problematic in this situation. Modified maximum likelihood (MML) estimation technique gives the opportunity to estimate model parameters in closed forms under non-normal distributions. Hence, the use of MML estimators in the test statistic is proposed for pairwise multiple comparisons under STS distribution. The efficiency and power comparisons of the test statistic based on sample mean, trimmed mean, wave and MML estimators are given and the robustness of the test obtained using these estimators under plausible alternatives and inlier model are examined. It is demonstrated that the test statistic based on MML estimators is efficient and robust and the corresponding test is more powerful and having smallest Type I error.     

Suitable Algorithm Associated with a Parameterization for the Three-Parameter Log-Normal Distribution

Associated with a parameterization for the three-parameter lognormal distribution, an algorithm was proposed by Komori and Hirose, which can find a local maximum likelihood (ML) estimate surely if it exists. Nevertheless, by Vera and Díaz-García it was shown that performance in finding a local ML estimate deteriorated by adopting the parameterization only and using other algorithm. In the present article, it will be shown that Komori and Hirose’s algorithm should be used for the parameterization. This work will also give MATLAB codes as a useful tool for the parameter estimation of the distribution.     

上市公司的债务重组若干问题研究

上市公司与关联企业之间的债务重组是我国具有典型意义的一类债务重组。但从以往的实践看,这些重组大部分对提高企业竞争力和持续发展力没有实质性作用。财政部修订后的《企业会计准则—债务重组》仍需要进一步完善。

“立人”:中国现代人本主义美育思想的价值追求

“立人”是中国现代人本主义美育思想家共同重视的核心问题,这是由中国现代历史的内在发展要求和审美活动的基本规律所决定的。“立人”呼唤具有新质的现代人格的出现,是推动社会进步的关键性因素,而在中国特殊的现实语境中,又普遍存在着“情感教育”的不足,导致“人的素质”的欠缺,因此从“立人”的现实要求出发,在美学活动的规律制约下,重视“人”的美育教育及其情感教育就成为极其重要的内容。
