本文推导出有重复观测因变量值的直线相关和回归分析,它适用于按自变量值整理的有因变慢值的频数、均数和标准差的资料。本文还提出一种反映回归直线拟合优度的新的相关系数。
This paper deduces the linear correlation and regression analysis of the dependent variable value of repeated observations. It is applicable to the data of frequency, mean and standard deviation due to degraded values sorted by the values of independent variables. This paper also proposes a new correlation coefficient that reflects the goodness of fit of the regression line.
