The concept of regression goes back to the mathematician Gauss, who talked about fitting a line through a scatter of points.
回归这个概念要追溯到数学家高斯,讨论的是从若干散点中切合出一条直线
What Gauss did was said, let's fit a line through the point-- the scatter of points--and that's called the regression line.
高斯说,做这样的一条直线,切合所有散点,这就是回归直线
