Carry‐over in cross‐over trials in bioequivalence: theoretical concerns and empirical evidence

There is now general agreement that pre‐testing for carry‐over in the AB/BA design is harmful and that efficient analysis of this design must proceed on the assumption that carry‐over has not affected the results to any appreciable degree. A general consensus has not been achieved in the case of higher‐order designs. Since particular forms of carry‐over can be estimated on a within‐patient basis and unbiased within‐patient treatment estimators are possible, some statisticians favour pre‐testing and some favour automatic adjustment for carry‐over. We present theoretical arguments that show that, just as in the AB/BA case, the strategy of pre‐testing is biased as a whole and also that the loss in terms of efficiency in adjusting is not negligible. We also present data from two large series of bioequivalence studies to provide empirical evidence that in this context carry‐over is either absent or rare. We conclude that adjusting or testing for carry‐over in bioequivalence studies is at worst harmful and at best pointless, and that this may also apply to other kinds of study.

The Design And Analysis of a Mixture Experiment on Glass Durability

This paper discusses the statistical design and analysis of a non–standard constrained mixture experiment on glass durability (the components sum to 1, and there are non–trivial lower or upper bounds on components or combinations of them). It notes some of the difficulties which arose during the study, and shows how the aims and methods of the experiment changed during its execution.     

Design and analysis of computer experiments when the output is highly correlated over the input space

To build a predictor, the output of a deterministic computer model or “code” is often treated as a realization of a stochastic process indexed by the code's input variables. The authors consider an asymptotic form of the Gaussian correlation function for the stochastic process where the correlation tends to unity. They show that the limiting best linear unbiased predictor involves Lagrange interpolating polynomials; linear model terms are implicitly included. The authors then develop optimal designs based on minimizing the limiting integrated mean squared error of prediction. They show through several examples that these designs lead to good prediction accuracy.     

数字生命的哲学思考

数字生命研究是新兴起的计算机与生物学交叉的前沿科学领域,主要是采取软件的形式在计算机中产生展示生命特征的人工生命实体。数字生命是虚拟实在的一种重要形式。“磁芯大战”、“Tierra世界”、Adida和“阿米巴世界”等是数字生命研究的几个重要模型。数字生命研究向我们提出了一系列哲学问题,其中主要有:数字生命是真实的生命或将成为真实的生命吗?数字生命世界与现实世界在本体论上等价吗?我们对制造数字生命承担伦理和法律责任吗?

电脑技术在艺术设计中的价值与流弊

电脑技术在设计中的应用,对提高设计效率起了积极的作用,为设计业的发展拓展了新的空间,与此同时,也带来了诸如设计手法、创意、质量等方面的流弊。为克服这些流弊,在构思一种设计时应徒手绘制草图,不囿于电脑软件提供的程式,在设计创作中积极探寻自己的、个性化的表现语言,以实现技术与艺术的统一。
