ALL-BIAS DESIGNS FOR POLYNOMIAL SPLINE REGRESSION MODELS

Polynomial spline regression models of low degree have proved useful in modeling responses from designed experiments in science and engineering when simple polynomial models are inadequate. Where there is uncertainty in the number and location of the knots, or breakpoints, of the spline, then designs that minimize the systematic errors resulting from model misspecification may be appropriate. This paper gives a method for constructing such all‐bias designs for a single variable spline when the distinct knots in the assumed and true models come from some specified set. A class of designs is defined in terms of the inter‐knot intervals and sufficient conditions are obtained for a design within this class to be all‐bias under linear, quadratic and cubic spline models. An example of the construction of all‐bias designs is given.     

全球化与武术文化世界化发展

全球化不仅仅局限于经济领域,还包括政治、军事、文化等领域,它实质是以西方发达资本主义国家集团为主导的,西方强势文化利用其资本、技术和市场优势对其他弱势文化的渗入、控制或强制“输出”。在西方“文明示范”面前,“拿来”的精神气魄固然重要,但“拿出”也同样不容忽视。当前,武术世界化发展过程中存在着过分偏重武术技术的推广和交流,而轻视武术文化的传播。因此,我们要把握全球化为武术文化世界化发展提供的历史契机,“推武术以布中外,敷文化以及四方。”     

塔山工业园发展循环经济的思路

塔山工业园发展循环经济,以资源的高效利用和循环利用为核心,将煤炭流动方式由传统的“资源-产品-废弃物”单向线型模式,转变为“资源-产品-废弃物-再生资源”闭合循环模式。通过在生产过程中贯彻“减量化、再使用、资源化”的减物质化原则,实现资源利用的最大化和废弃物排放的最小化,从而达到提高能源利用率、改善生态环境、提高经济效益的目的。

Kernel Estimation of Rate Function for Recurrent Event Data

Abstract.  Recurrent event data are largely characterized by the rate function but smoothing techniques for estimating the rate function have never been rigorously developed or studied in statistical literature. This paper considers the moment and least squares methods for estimating the rate function from recurrent event data. With an independent censoring assumption on the recurrent event process, we study statistical properties of the proposed estimators and propose bootstrap procedures for the bandwidth selection and for the approximation of confidence intervals in the estimation of the occurrence rate function. It is identified that the moment method without resmoothing via a smaller bandwidth will produce a curve with nicks occurring at the censoring times, whereas there is no such problem with the least squares method. Furthermore, the asymptotic variance of the least squares estimator is shown to be smaller under regularity conditions. However, in the implementation of the bootstrap procedures, the moment method is computationally more efficient than the least squares method because the former approach uses condensed bootstrap data. The performance of the proposed procedures is studied through Monte Carlo simulations and an epidemiological example on intravenous drug users.
