同學你好，
根據(jù)最新的原版書勘誤：
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.（勘誤的是這兩段話，之前的原版書這兩個結論表述有問題）
現(xiàn)在我們的講義上根據(jù)勘誤改對了，所以老師應該提了一下。
