一.直线回归方程间有无区别的判别问题 1.《理化检验》化学分册第16卷第5期“利用回归分析方法计算吸光度分析结果”-文中提出如下判别式: ?? 并确定t≤2时判两个直线回归方程无区别,可以进行合并应用的看法.我们在应用中曾多次出现一些错判的现象,经研究认为用(1)式来判别分析化学领域中的回归方程之间的区别问题存在局限性,现将(1)式通过关系式转化成
A linear regression equation between the distinction between the discriminant 1. “Physical and Chemical Testing” Volume 16, Volume 5, “using regression analysis method to calculate the absorbance analysis results” - the following formula is proposed: ?? and determine t? 2 When the two linear regression equation is judged to be no difference, can be combined with the application of the view we have repeatedly appeared in the application of some wrong judgments phenomenon, the research that the use of (1) to determine the analytical chemistry in the field of regression equations There is a limitation of the difference between the two types of problems. Now equation (1) is transformed into a relation
