推进马克思主义中国化的动力要素研究

推进马克思主义中国化的动力是一个极其复杂的系统,它包含着诸多要素,有变量和不变量。其中,理论前提、文化环境是不变量;国情条件、实践基础、逻辑主题、实现主体等要素均为变量。这些变量与不变量相互影响、相互作用共同构成了马克思主义中国化的动力要素。     

Parameterization and inference for nonparametric regression problems

We consider local likelihood or local estimating equations, in which a multivariate function () is estimated but a derived function () of () is of interest. In many applications, when most naturally formulated the derived function is a non-linear function of (). In trying to understand whether the derived non-linear function is constant or linear, a problem arises with this approach: when the function is actually constant or linear, the expectation of the function estimate need not be constant or linear, at least to second order. In such circumstances, the simplest standard methods in nonparametric regression for testing whether a function is constant or linear cannot be applied. We develop a simple general solution which is applicable to nonparametric regression, varying-coefficient models, nonparametric generalized linear models, etc. We show that, in local linear kernel regression, inference about the derived function () is facilitated without a loss of power by reparameterization so that () is itself a component of (). Our approach is in contrast with the standard practice of choosing () for convenience and allowing ()> to be a non-linear function of (). The methods are applied to an important data set in nutritional epidemiology.     

统计在社会科学领域应用的新进展及反思

社会科学的核心问题是解释社会系统的活动,包括社会现象、社会行为和社会过程。一般认为,社会科学主要包括人类学、社会学、心理学、经济学、教育学、管理学等。对现代科学尤其是社会科学而言,研究方法,特别是统计技术上的进步在很大程度上能够起到推动整个学科发展的作用。由于社会科学的研究对象常常是社会、组织和个人的一些特征,这些特征常常过于抽象,不能直接测量,而社会科学所涉及的变量又几乎都是随机变量,这些变量的数据规模也常常很大,因而,社会科学的量化水平相对于自然科学而言常常较低,许多研究常常依赖于概念的定义和逻辑推理…     

《中华人民共和国统计法》的特色

《中华人民共和国统计法》已于1983年12月8日以中华人民共和国主席会第九号公布,从1984年1月1日起在全国范围内施行。《统计法》的实施,是加强我国统计工作,促进统计工作现代化的一项重大措施,并将对整个社会主义现代化建设事业产生积极的影响。     

煤炭资源开采中的生态环境经济损失及补偿研究

通过对CVM研究结论的比较讨论,认为基于CVM测算出的煤炭资源开采中的生态环境经济损失值偏小.为了全面计算煤炭资源开采中的生态环境经济损失值,提出将CVM与直接市场法和间接市场法联合使用,并计算出2010年榆林市煤炭资源开采的生态环境经济损失为208.4亿～209.11亿元.在此基础上,又对煤炭资源开采中的生态环境损失补偿问题进行研究,提出由煤炭资源开采企业和煤炭资源受益者共同承担煤炭资源开采中生态环境损失补偿的责任,并对各自应该分担的补偿水平进行量化.     

基于改进D—S证据理论的TOPSIS模型在科技奖励评价中的应用

针对科技奖励评价的特点,根据改进D—S证据合成规则,将专家的评价指标值转化为指标的综合得分并形成决策矩阵;结合TOPSIS模型求解理想解和负理想解,计算距离和贴近度,对各评价项目进行综合排名。实证结果表明：该模型能够很好地解决科技奖励评价过程中的不确定性问题,为科技奖励综合评价提供了一种新的思路。     

Model averaging for M-estimation

M-estimation is a widely used technique for robust statistical inference. In this paper, we study model selection and model averaging for M-estimation to simultaneously improve the coverage probability of confidence intervals of the parameters of interest and reduce the impact of heavy-tailed errors or outliers in the response. Under general conditions, we develop robust versions of the focused information criterion and a frequentist model average estimator for M-estimation, and we examine their theoretical properties. In addition, we carry out extensive simulation studies as well as two real examples to assess the performance of our new procedure, and find that the proposed method produces satisfactory results.     

Generalized Analysis-of-variance-type Test for the Single-index Quantile Model

In this paper, we are concerned with a test for the index parameter and index function in the single-index model. Based on the estimates obtained by the quantile regression, we extend the generalized analysis-of-variance-type test to the single-index model. We investigate the asymptotic behavior of the proposed test and demonstrate that its limiting null distribution follows an asymptotically χ²-distribution. The simulation studies and real data applications are conducted to illustrate the finite sample performance of the proposed methods.
