The claim is, I can write any vector you give me as a real scale i plus a real scale j.
也就是说,我可以把任何你给我的矢量,写成 i 和 j 的实系数线性组合的形式
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。
