利用多元线性回归方程可以对与y相关的变量进行拟合。拟合的过程可以分为多个步骤先拟合一个与y相关的变量然后逐步加入更多的相关变量直到所有相关变量都被拟合为止。 翻译

Using multiple linear regression equations, variables related to y can be fitted. The fitting process can be divided into multiple steps, first fitting a variable related to y, and then gradually adding more related variables until all related variables are fitted.
