官方DOE Guide Ver9.0,第126页原文如下:
This example shows a power analysis for the Catalyst variable, using default value for α (0.05), the root mean square error and parameter estimate for Catalyst, for a sample size of 12. The resulting power is 0.802, which means that in similar experiments, you can expect an 89% chance of detecting a significant effect for Catalyst.
其中检验功效如果是0.802的话,是不是发现显著性差异的几率为80%啊?怎么书中说是89%呢?请杨老师帮忙解答,先谢过了! |
