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

Again, I'm not going to spend much time on this, of the ith asset is the regression coefficient when you regress the return on the ith asset on the return of the market portfolio.

再强调一次，我不打算花太多时间在这个等式上面，但要注意的是当你想将市场组合收益，but，the，β,回归到第i资产收益中去,第i资产β系数是线性回归方程的,回归系数。
