CAR系统的回归分析法应用及其他

作者和他的合作者开发的计算机辅助试验研究系统（简称CAN系统）是一个试验设计的专门应用软件，由正交试验法和回归分析法两大部分组成，以一个三变量多性能指标的丁精橡胶配方设计（三元二次回归模型）为例，说明了CAR系统回归分析法部分的回归试验设计、回归方程的获取与显著性检验、预测和优选配方等试验设计功能和其他情况，并且结合这个实例讨论了应用回归分析法有时被忽视的几个基本问题：回归方程的显著性检验，重复试验和拟合检验，回归系数的显著性检验，对食不显著项回归方程的处理，剩余标准高差，回归正交设计和自变量编码等。

Application of Regression Analysis Method in the Computer Aided Research System and Others

The Computer Aided Research (CAN) mtem programmed by the author et al. is anapplication software on the multivariable statistical analysis. It's composed of both the sectionorthonormal test method and the section regression analrris method. The functbo of test desgn inthe section of regression analguis methed, such as the plan design of regression experiments, theobtainment of regression equation and the test of significance, the forecast and the compoundoptimization, havc been demonstrated. At the same time, the basic questions of applyingregression analysis, which are ignored sometimes, Such as the tcst of Significance of regressionequahon, the duplication experiments and the fit test, the test of significance of regrchioncoefficients the treatmcnt of regression equation with unstriking clause, the standard remaindervibration, and the standardizing unit of the variants in the orthonormal design of rcgressionexperiments , have also been discussed by an example of nitrile rubber that is three variant andpoytarget variable problem (application of ternary quadratic regression model).
