配料混合试验的设计和分析

Design and Analysis for Experiments with Mixtures

系统地介绍了配料混合试验的基本概念,指出了混合试验与常规因子试验的区别。提出配料混合试验的3种设计,即顶点和边界点设计、矩心设计和极顶设计。以2个实例演示了混合试验资料的统计方法,包括回归和方差分析,驻点分析和等值线分析。

The basic concept on mixture experiments of ingredients was systematically introduced, and the distinction was showed between the mixture and conventional factor experiments. Three basic designs for mixture experiments, i.e., apex and boundary point design, centroid design and extreme vertex design, were presented. Two real examples were given to demonstrate the statistical method for the data from mixture experiments, including the analyses of regression and variance, stationary point and contours.
