同学你好,
根据最新的原版书勘误:
If a strategy’s 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.
A Type II error would be trimming or not hiring strong performers and hiring managers with weaker track records.(勘误的是这两段话,之前的原版书这两个结论表述有问题)
现在我们的讲义上根据勘误改对了,所以老师应该提了一下。
