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。

And you will see data points which scatter around a straight line.

你可以看到这些点，分布在一条直线周围。

To take an extreme example, imagine that an electron does not scatter in an iron layer unless its spin points in the same direction as the layer's magnetization.

举一个极端的例子，假设一个电子没有在一个铁层散射，除非与层的磁化方向相同地旋转。

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

This could be 1979, this could be 1980, and we keep adding points so we have a whole scatter of points.

假设这里是1979年,这里是1980年,一直添加数据点,就形成了一个散点图
