摘要
分析一元线性回归系数的相关性,导出一元线性回归系数比值不确定度的计算公式,指出了某些文献中有关回归系数比值不确定度评定存在的问题.
In this paper regression coefficient correlation was analyzed and the formula of uncertainty of regression coefficient ratio in one dimensional linear regression equation was derived. The shortcomings in some documents about the evaluation of uncertainty of regression coefficient ratio were pointed out in this paper.
