这篇论其实际比较像... 第二点五篇？ XD （方法的问题当然很重要，可专门开
一篇在讲这个... 读起来实在挺累人。 lol）
摘录几句以备参考。
... So instead of looking at these results and concluding that fielding
percentage is not a significant measure of fielding performance, a lot
of very smart people instead decided that fielding is not a significant
part of playing baseball. This is not a consequence of regression, this
is a consequence of not doing it correctly.
"This is what my regression says" is not a defense of the assumptions
made when creating the regression. You are responsible for what goes into
your regression, and so you're accountable for what comes out of your
regression. It's as simple as that. If advanced econometric techniques
are capable of the role they've played in our current economic downturn,
they can certainly make mistakes on how much baseball players should be
paid. ...
似乎不像是多真正的棒球文呴。

: 里头又是经常忘记、又是通通忘记的，显然又是篇不真正棒球文。

: 第一篇介绍了两种评估的方法（marginal-revenue-product 以及 free-market-
: return），第二篇则用方法一试算了一下，其间并穿插说明相关背景知识、不同评
: 估方法各自面临的侷限、跑回归时要有的心理准备等。
