Fundamental Equations of BLUE and BLUP in the Multivariate Linear Model with Applications

Ordinary least squares estimator (OLSE), best linear unbiased estimator (BLUE), and best linear unbiased predictor (BLUP) in the general linear model with new observations are generalized to the general multivariate linear model. The fundamental equations of BLUE and BLUP in the multivariate linear model are derived by two methods, including the vectorization method and projection method. By using the matrix rank method, some new results of linear BLUE-sufficiency, linear BLUP-sufficiency, and the equality of OLSE, BLUE, and BLUP are given in the multivariate linear model.     

Consistency and Normality of M-Estimators in Partly Linear Models with Stochastic Adapted Errors

The robust M-estimators for the partly linear model under stochastic adapted errors are considered. It is shown that the M-estimator of parameter is asymptotically normal and the M-estimator of the nonparametric function achieves the optimal rate of convergence for nonparametric regression. Some known results are improved and generalized. Some simulations and a real data example are conducted to illustrate the proposed method.     

Some Theoretical Comparisons of Negative Binomial and Zero-Inflated Poisson Distributions

In this article, we compare the zero-inflated Poisson (ZIP) and negative binomial (NB) distributions based on three most important criteria: the probability of zero, the mean value, and the variance. Our results show that with same mean value and variance, the ZIP distribution always has a larger probability of zeros; with same mean value and probability of zeros, the NB distribution always has a larger variance; and with same variance and probability of zeros, the ZIP distribution always has a larger mean value. We also study the properties of Vuong test in model selection in three cases by simulations.     

A Simple Method Using CuScore to Monitor Changes in ARMA Coefficients

This paper suggests a simple nonmetric method for smoothing time series data. The smoothed series is the closest polytone curve to the presmoothed series in terms of least sum of absolute deviations. The method is exemplified on several seasonally adjusted series in order to estimate their trend component.

论高校家庭经济困难学生人际适应性素质的培育

人际适应是社会适应的一个最基础和重要的方面,没有人际交往,谈不上社会适应。高校家庭经济困难学生的人际适应不良现状,迫切需要从如下几方面来对贫困生人际适应性素质进行培育:一是经济扶贫与精神扶贫相结合;二是人事智能培育;三是优化校园潜课程建设。     

"三农"视野下的《农业与工业化》——张培刚"三农"经济思想研究

民国时期海外留学生的经济学学术成就普遍未得到学术界的重视和认可,而事实上,这一时期的海外留学生在留学期间运用西方现代经济学理论和方法研究了中国的大量的经济问题,并取得了显著的成就。本文以"三农"为视角剖析了张培刚在哈佛大学的博士论文《农业与工业化》,重点研究了张培刚从静态与动态视野下对农业与工业化关系的论述,以此管窥民国时期海外攻读博士学位的留学生在留学期间对于"三农"问题研究方面所取得的学术成就。     

我国电信行业管制中的上限价格理论应用

实施上限管制是电信资费管理方式改革的主要内容,同时也是提高消费者福利的重要手段。通过梳理上限管制的理论、国外实践、趋势判断与中国电信资费监管存在的问题,阐述了我国电信行业的价格上限管制的改革的必要性与可行性,描述了上限管制的制度创新与发展历程,并首次对长途电话业务的上限管制政策的实施效果进行评估,最后提出了我国上限管制存在的问题及完善措施。     

解析《诗经·卫风》中展现的卫国经济

《诗经.卫风》因较多为情诗,古往今来的史学家对其研究的重点往往放在"乱世之音"、"靡靡之音"上,而对诗歌中折射出的卫国经济生活、婚恋习俗等关注甚少。鉴于此,该文试图通过对《卫风》中有关社会经济描写的关注,顺着卫人的眼光与思维,撩开卫国经济发达的另一个侧面。     

捐赠文化缺失的社会环境创生

慈善事业的发展需要捐赠文化及其社会环境,但由于多种原因致使我国捐赠文化严重缺失。我们可以通过整合国内外优秀文化资源,逐渐培育捐赠文化生态;强化公众教育,形成全民慈善捐赠理念;完善企业文化内涵,增强企业社会责任感;正确评价和引导社会捐赠理念和行为等多条渠道或多种方式创生捐赠文化的社会环境,以大力促进我国慈善事业的发展,推进和谐社会的构建。
