Computation of finite population parameters and approximate probability values for multi-response randomized block permutation procedures (mrbp)

An algorithm is presented for computing the finite population parameters and the approximate probability values associated with a recently-developed class of statistical inference techniques termed multi-response randomized block permutation procedures (MRBP).     

Response predictions in regressions on panel data

In this paper we consider the problem of obtaining best linear unbiased estimators of individual response coefficients in a Random Coefficient Linear Regression (RCR} Model, comparing alternative estimators for these response vectors through a simulation study. We also provide an empirical example that illustrates the estimation procedure proposed here.     

Four Correlation Coefficients with a Third Blocking Variable: Their Efficacy,Relative Efficiency,and Test Statistics

Abstract

The efficacy and the asymptotic relative efficiency (ARE) of a weighted sum of Kendall's taus, a weighted sum of Spearman's rhos, a weighted sum of Pearson's r's, and a weighted sum of z-transformation of the Fisher–Yates correlation coefficients, in the presence of a blocking variable, are discussed. The method of selecting the weighting constants that maximize the efficacy of these four correlation coefficients is proposed. The estimate, test statistics and confidence interval of the four correlation coefficients with weights are also developed. To compare the small-sample properties of the four tests, a simulation study is performed. The theoretical and simulated results all prefer the weighted sum of the Pearson correlation coefficients with the optimal weights, as well as the weighted sum of z-transformation of the Fisher–Yates correlation coefficients with the optimal weights.     

Planning for the 1950 Censuses of Population and Agriculture

The change from the z of “Student's” 1908 paper to the t of present day statistical theory and practice is traced and documented. It is shown that the change was brought about by the extension of “Student's” approach, by R.A. Fisher, to a broader class of problems, in response to a direct appeal from “Student” for a solution to one of these problems.     

An Improved Boxplot for Univariate Data

The boxplot is an effective data-visualization tool useful in diverse applications and disciplines. Although more sophisticated graphical methods exist, the boxplot remains relevant due to its simplicity, interpretability, and usefulness, even in the age of big data. This article highlights the origins and developments of the boxplot that is now widely viewed as an industry standard as well as its inherent limitations when dealing with data from skewed distributions, particularly when detecting outliers. The proposed Ratio-Skewed boxplot is shown to be practical and suitable for outlier labeling across several parametric distributions.     

思想政治教育网络传播受众动机特征及对策分析

受众是思想政治教育网络传播的重要构成要素,研究受众接受动机成为提高思想政治教育网络传播效果的关键。思想政治教育的受众具有求知、交流、宣泄、求实和自我实现的动机,尊重受众的知情权,增强互动设置,提供适当的宣泄平台,加强网站的服务性功能,提高可供受众创造力发挥的平台是基本的对策。     

企业非确定型决策与中庸

在企业常用的非确定型决策方法中 ,决策者对未来所持的态度不同 ,选择的方案就不同。如何保持正常的心态 ,作出科学的选择 ,这一思想正好与中国传统文化中道德领域的中庸相一致。中庸强调“既不太过 ,也不不及” ,保持“适中”的人生态度。古为今用 ,不同领域 ,问题的根本都是对不确定型问题的决策

产品品种繁多类型企业投入产出表的处理思想与方法

对于生产装配性产品的机械企业，由于产品与原材料种类繁多，将造成企业投入产出表的规模庞大，致使投入产出表的编制、计算和使用产生诸多问题，甚至难以实现。为了控制表的规模，常采用将消耗量相近、生产工艺相近的产品合并的做法。但这种做法严重影响了投入产出表的精度和应用效果。因此，本文讨论了更为有效的解决这类问题的思想和方法。
