同學(xué)你好,
根據(jù)最新的原版書(shū)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(shū)這兩個(gè)結(jié)論表述有問(wèn)題)
現(xiàn)在我們的講義上根據(jù)勘誤改對(duì)了,所以老師應(yīng)該提了一下。
