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
It's not extensive in the sense that you just have to scatter your stuff over wide fields; that's not what it is.
它不是你泛泛的在宽广的,土地上播种就够了,它并非只是这样
But the hypothesis was based on this association more or less, that looked at the rates of breast cancer across different countries and how much dietary fat those countries consumed and so you get a nice little scatter plot.
但以上假说,多少也基于一些合作研究,看看乳腺癌在不同国家,的发病率,那些国家在饮食中摄入了多少脂肪,然后就会得到一个不错的散点图
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
Let's draw a line through a scatter of points here.
我们来画一条切合散点的直线
