Economic-statistical design of X ¥ charts for non-normal data by considering quality loss

When the X ¥ control chart is used to monitor a process, three parameters should be determined: the sample size, the sampling interval between successive samples, and the control limits of the chart. Duncan presented a cost model to determine the three parameters for an X ¥ chart. Alexander et al. combined Duncan's cost model with the Taguchi loss function to present a loss model for determining the three parameters. In this paper, the Burr distribution is employed to conduct the economic-statistical design of X ¥ charts for non-normal data. Alexander's loss model is used as the objective function, and the cumulative function of the Burr distribution is applied to derive the statistical constraints of the design. An example is presented to illustrate the solution procedure. From the results of the sensitivity analyses, we find that small values of the skewness coefficient have no significant effect on the optimal design; however, a larger value of skewness coefficient leads to a slightly larger sample size and sampling interval, as well as wider control limits. Meanwhile, an increase on the kurtosis coefficient results in an increase on the sample size and wider control limits.

Sparse additive models

Summary.  We present a new class of methods for high dimensional non-parametric regression and classification called sparse additive models. Our methods combine ideas from sparse linear modelling and additive non-parametric regression. We derive an algorithm for fitting the models that is practical and effective even when the number of covariates is larger than the sample size. Sparse additive models are essentially a functional version of the grouped lasso of Yuan and Lin. They are also closely related to the COSSO model of Lin and Zhang but decouple smoothing and sparsity, enabling the use of arbitrary non-parametric smoothers. We give an analysis of the theoretical properties of sparse additive models and present empirical results on synthetic and real data, showing that they can be effective in fitting sparse non-parametric models in high dimensional data.     

Bayesian analysis of a general growth curve model with predictions using power transformations and AR(1) autoregressive dependence

In this paper, we consider a Bayesian analysis of the unbalanced (general) growth curve model with AR(1) autoregressive dependence, while applying the Box-Cox power transformations. We propose exact, simple and Markov chain Monte Carlo approximate parameter estimation and prediction of future values. Numerical results are illustrated with real and simulated data.

中国传统手工艺文化重建的路径分析

工业社会各种文化对传统手工艺文化的冲击和破坏是当前传统手工艺传承和保护困难的原因之一。适应当代社会文化发展的需要,重建传统手工艺文化是促进当前手工业发展的必要工作之一。要明确我国传统手工艺文化的突出特征以及文化重建的内涵。应结合现代工业文化的影响,对传统手工艺文化进行有重点的重建。重建的关键路径是,适应现代企业经营理念,重建传统手工业企业的经营文化和技艺传承文化,同时激发社会对传统手工艺文化的消费需求。     

科斯定理与中国经济改革——从“产权—交易费用”的视角进行解释

以科斯定理为基础,从产权界定与交易费用视角分析1978年以来中国经济改革的政策进行解释,研究发现,在1978—1992年和1992—2008年的两个阶段里,中国因为"摸着石头过河"找到了适合国情的产权界定与保护方法,使得市场价格机制得以运行,全社会的交易费用随之下降,赢得了经济的高速增长。然而,近年来中国部分经济改革措施却与产权保护、降低交易费用相悖,使得经济出现了不可避免的困难。     

“中国模式”对马克思主文中国化的作用

“中国模式”对马克思主义中国化历史发展和理论成果具有重要的作用。具体表现在：“中国模式”内容要素是马克思主义中国化理论成果的重要组成部分;“中国模式”各要素的和谐运行是马克思主义中国化理论成果尤其是中国特色社会主义理论体系发展的重要条件;“中国模式”的成功是马克思主义中国化即马克思理论基本原理与中国实际相结合正确性的强有力的证明。     

企业文化的道德审视——问题奶粉事件所引发的思考

本文以对问题奶粉事件的思考为契机,梳理了企业文化与道德融合的历程,指出企业文化在一定意义上能够促成企业道德氛围,但企业道德氛围存在重大隐患——“内部道德”现象,它对企业成员道德推理产生不利影响,问题奶粉事件集中体现了“内部道德”作用下的消极结果。本文还进一步探讨了改进企业道德氛围的相关建议。
