第二讲饱和D—最优设计最优设计是在各种设计方案中最大方差为最小的一种设计方案。该设计方案的预测值精度较高,对选择最佳生产措施有较强的实用性。饱和最优设计又是回归方程中参数数目与试验处理组合数目相等的设计,回归自由度与总自由度相等达到饱和。采用这种设计进行科学研究,试验处理数较少,而获得的信息较多,误差小、精度高,能收到事半功倍的效果。
Lecture 2 Saturated D-Optimal Design The optimal design is the one with the smallest variance among the various designs. The design of the forecasting value of high accuracy, the selection of the best production practices have strong practicality. Saturation optimal design is again the regression equation in the number of parameters and experimental treatment of the same number of combinations of design, regression degree of freedom equal to the total degree of freedom saturation. Using this design for scientific research, the experimental treatment less, and get more information, error is small, high precision, can receive a multiplier effect.
