A new heavy-tailed distribution defined on the bounded interval: the logit slash distribution and its application

This paper proposes a new heavy-tailed and alternative slash type distribution on a bounded interval via a relation of a slash random variable with respect to the standard logistic function to model the real data set with skewed and high kurtosis which includes the outlier observation. Some basic statistical properties of the newly defined distribution are studied. We derive the maximum likelihood, least-square, and weighted least-square estimations of its parameters. We assess the performance of the estimators of these estimation methods by the simulation study. Moreover, an application to real data demonstrates that the proposed distribution can provide a better fit than well-known bounded distributions in the literature when the skewed data set with high kurtosis contains the outlier observations.     

我国马克思主义学科体系建设的战略思考

马克思主义学科体系建设不仅直接关系到哲学社会科学的繁荣和发展,而且也关系到党和国家的命运前途。马克思主义学科具有独特的内涵和功能,初创时期可由五个二级学科构成。马克思主义学科体系建设首先必须明确一系列基本问题;马克思主义理论教育教学是推动马克思主义学科体系建设的重要途径和手段。     

Double and group acceptance sampling plan for truncated life test based on inverse log-logistic distribution

This paper introduces a double and group acceptance sampling plans based on time truncated lifetimes when the lifetime of an item follows the inverse log-logistic (ILL) distribution with known shape parameter. The operating characteristic function and average sample number (ASN) values of the double acceptance sampling inspection plan are provided. The values of the minimum number of groups and operating characteristic function for various quality levels are obtained for a group acceptance sampling inspection plan. A comparative study between single acceptance sampling inspection plan and double acceptance sampling inspection plan is carried out in terms of sample size. One simulated example and four real-life examples are discussed to show the applicability of the proposed double and group acceptance sampling inspection plans for ILL distributed quality parameters.     

试论民族文化认同的特殊功效--从斯大林民族定义的争论说开去

文化具有超时空的稳定性和很强的凝聚力,一个民族的文化模式一经形成,必然会持久地支配每个社会成员的思想和行为。文化又是一个民族区别于其他民族的基本特质和身份象征,在共同的文化背景中,人们获得了归属感和认同感。因此,在共同文化基础上形成的共同心理素质——民族文化认同,对于标识民族特性,塑造认同心理,规范社会行为,培育统一意识,凝聚民族精神,形成民族合力,进而对维护国家安全统一具有特殊的功效。     

A general central limit theorem and a subsampling variance estimator for α‐mixing point processes

We establish a central limit theorem for multivariate summary statistics of nonstationary α‐mixing spatial point processes and a subsampling estimator of the covariance matrix of such statistics. The central limit theorem is crucial for establishing asymptotic properties of estimators in statistics for spatial point processes. The covariance matrix subsampling estimator is flexible and model free. It is needed, for example, to construct confidence intervals and ellipsoids based on asymptotic normality of estimators. We also provide a simulation study investigating an application of our results to estimating functions.     

Toward an integrated Bayesian network approach to measurement error detection and correction

In this article, the quality of data produced by national statistical institutes and by governmental institutions is considered. In particular, the problem of measurement error is analyzed and an integrated Bayesian network decision support system based on non-parametric Bayesian networks is proposed for its detection and correction. Non-parametric Bayesian networks are graphical models expressing dependence structure via bivariate copulas associated to the edges of the graph. The network structure and the misreport probability are estimated using a validation sample. The Bayesian network model is proposed to decide: (i) which records have to be corrected; (ii) the kind and amount of correction to be adopted. The proposed correction procedure is applied to the Banca d’Italia Survey on Household Income and Wealth and, specifically, the bond amounts are analyzed. Finally, the sensitivity of the conditional distribution of the true value random variable given the observed one to different evidence configurations is studied.     

A new infinitely divisible discrete distribution with applications to count data modeling

A new discrete distribution involving geometric and discrete Pareto as special cases is introduced. The distribution possesses many interesting properties like decreasing hazard rate, zero vertex uni-modality, over-dispersion, infinite divisibility and compound Poisson representation, which makes the proposed distribution well suited for count data modeling. Other issues including closure property under minima, comparison of its distribution tail with other distributions via actuarial indices are discussed. The method of proportion and maximum likelihood method are presented for parameter estimation. Finally the performance of the proposed distribution over other classical and newly proposed infinitely divisible distributions are discussed.     

河北省经济增长与就业结构的变动分析

随着资本投入的增长和技术的进步,经济的增长将大量未充分就业的农业劳动力向高生产率部门转移而导致就业结构变化,就业结构的变动又进一步促进了经济的增长.试图从生产函数出发,将就业结构变动从全要素生产率中分离出来,得出就业结构变动对经济增长的推动效应及第一产业就业人口向第二三产业的流动对经济增长的贡献.     

当代民间信仰研究的现状和走向思考

当代中国思想文化一个无可回避的事实,就是如何看待现实社会中广泛存在的民间信仰.近几年,学界对什么是民间信仰,展开热烈的讨论,有关"民间信仰"的定义也众说纷纭,但是,大多论者对民间信仰往往只注意其信仰的层面,并以宗教学的知识、理论进行解说,缺乏该信仰与现实社会关系的研究.新的研究走向,拟从当代社会流行的民间信仰和民众生活的关系,从一种不脱离信仰的生活切入,以点带面,实践调查,理性分析,科学界定,并在此基础上提出相应的对策,为国家对民间信仰的管理提供政策的依据,为中国现当代思想文化建设做出应有的贡献.
