老师，我确认一下，joint optimization对冲外汇风险，贝塔1和贝塔2都是hedge ratio吗。还是只有其中一个是？

請問 “The extent to which markets are mean-reverting also has a bearing on the cost of Type I and Type II errors. If performance is mean reverting, firing a poor performer (or hiring a strong performer) only to see a reversion in performance results is a Type I error.” 如果是 mean reverting, firing a poor performer。不是代表現在開除表現差的PM其實表現好，那不是type ii error嗎?

請問 “The smaller the difference in sample size and distribution mean and the wider the dispersion of the distributions, the smaller the expected cost of the Type I or Type II error.” 中The smaller the difference in sample size and distribution mean這段話可以舉實例嗎?

想請問三級衝刺筆記page225中兩題的Non-systematic risk的算法為什麼不一樣呢? 謝謝
