摘要
本文提出把可控变量与随机变量更换位置,运用最小二乘法求出可控变量关于随机变量的另一条近似直线X=α_0+α_1Y,并用所求直线X=α_0+α_1Y,与回归直线X=b_0+b_1X之间的夹角来评判变量之间线性相关关系是否显著。
By exchanging the position of independent variable and random independent variable and using the
least square method, another approximate line X=a0=a1Y about independent variable and random variable can be
obtained. The significance of correlativity is able to be tested by observing the angle between the line X=a0=a1 Y and regresion line Y=b0=b1 X.
