摘要
对原有的模型作了改进,增强了逼近效果。并能使模型在回归显著性检验、可靠度误差分析等方面作理论分析。此方法适用面较宽,应用于文中所举实例,获得满意的结果。
We improved the original model of reference paper [1],and increased the approxi-mate efficiency. And meanwhile, the improved model can be used for theoretical analy-sis of regression test and reliability error analysis. The illustrated examples in the paper show that this method is suitable for many practical cases.
