Estimation of weibull location

A simulation study was carried out to compare the performances of two different simple estimators of the location parameter for a three-parameter Weibull distribution Both Estimators have been suggested by recent paper in the literature. Bras and mean square error are examined for many different sample-size and shape-parameter-value combinations. Strong evidence of the domination of one estimator over the other is found.     

《一报还一报》的伦理混乱与秩序重构中的悲喜命运转向

莎士比亚《一报还一报》一剧以克劳狄奥与朱丽叶的婚前私通为主要伦理线,展示了维也纳法治下个人私通和公共淫乱两类人的跌宕命运,着重探讨了维也纳城的伦理混乱,以及在主政者的伦理秩序重构中个人私通者由悲而喜和公共淫乱者由喜而悲的命运转向,旨在指出在西方前现代社会中,对基督教伦理规范的认同与否决定着个人的命运转向。     

A note on the mean residual life of a coherent system with a cold standby component

In this paper, we investigate the effect of a cold standby component on the mean residual life (MRL) of a system. When the system fails, a cold standby component is immediately put in operation. We particularly focus on the coherent systems in which, after putting the standby component into operation, the failure of the system is due to the next component failure. For these systems, we define MRL functions and obtain their explicit expressions. Also some stochastic ordering results are provided. Such systems include k-out-of-n systems. Hence, our results extend some results in literature.     

Likelihood ratio order of parallel systems under multiple-outlier models

This paper studies the likelihood ratio ordering of parallel systems under multiple-outlier models. We introduce a partial order, the so-called θ-order, and show that the θ-order between the parameter vectors of the parallel systems implies the likelihood ratio order between the systems.     

彝族古籍文献《苏巨黎咪》的秩序观念建构

彝族古籍文献《苏巨黎咪》产生于唐朝初至中叶，记述了从上至君长到下至百姓的各种传统道德观念，蕴含着对秩序观念的建构，是彝族传统文化的重要载体。其主要内容可归结三个层面：强调君臣关系下的忠臣观念；以君主为主体的尚贤爱民的治理观；孝悌亲友、崇祖敬毕的和谐观及爱美向善的仁义观。该书是作者通过对儒家文化的学习以及有选择性地吸收和融合的产物，体现出作者出于维护统治者利益的、对稳定社会秩序的追求，把下层和上层、边缘和主流联系了起来，增强了族群凝聚力和认同感，维护了君长统治和社会稳定，推动了当时彝族社会的良性转型和健康发展。     

慈善与慈善组织的秩序维度与政策选择

人是生活在秩序维度的，人的生命的价值，尤其是劳动力的价值，与处于不同秩序维度有关系。公共慈善也是如此。它有原始秩序的维度，也有扩展秩序的维度，在不同的维度里，有不同的价值。从特朗普家族慈善基金会的命运，可以见出慈善和慈善组织涉及到的不同维度秩序的冲突。更好地发展慈善和慈善组织，需要解决冲突，在不同的秩序维度里，处理好各个方面的关系。     

词序像似性研究及实例分析

像似性是相对任意性而言的。语言像似性是指语言形式或结构与其所表达的概念之间存在对应关系,而词序像似性是指词的组织形式和人的认知结构之间有某种对应关系,主要受四个原则支配:顺序像似原则、距离像似原则、与说话人接近原则和文化规约像似原则。正确理解词序像似性的概念和原则,对目标语的学习有重要的指导意义。     

The generalized odd half-Cauchy family of distributions: Properties and applications

We introduce and study general mathematical properties of a new generator of continuous distributions with one extra parameter called the generalized odd half-Cauchy family. We present some special models and investigate the asymptotics and shapes. The new density function can be expressed as a linear mixture of exponentiated densities based on the same baseline distribution. We derive a power series for the quantile function. We discuss the estimation of the model parameters by maximum likelihood and prove empirically the flexibility of the new family by means of two real data sets.     

The Kumaraswamy GEV distribution

The popular generalized extreme value (GEV) distribution has not been a flexible model for extreme values in many areas. We propose a generalization – referred to as the Kumaraswamy GEV distribution – and provide a comprehensive treatment of its mathematical properties. We estimate its parameters by the method of maximum likelihood and provide the observed information matrix. An application to some real data illustrates flexibility of the new model. Finally, some bivariate generalizations of the model are proposed.
