| 摘 要： | 提出双方差回归模型,建立双方差回归分析方法,给出其回归方程和高置信水平、高可靠度的置信限曲线。双方差回归模型包含完全相关随机变量和相互独立随机变量,前者可用相关方差表征,后者则需用独立方差描述。传统回归分析主要适用于处理在一条曲线上随机波动的数据,而文中方法则可处理在多条不同曲线上随机波动的数据。在性能曲线测试中,文中方法与成组试验法相比,具有信息量大、精度高,所需试样少的特点。

| Abstract: | The two-variance regression model is put forward,on the basis of which the two-variance regression analysis method is established.Then the regression equation and confidence limit curves with high confidence level and high reliability are also given.The two-variance regression model involves totally correlated random variable and independent random variable which can be represented by correlated variance and independent variance,respectively.The presented method extends the regression analysis,which is main... |
