Bayesian vs Frequentist

Things on this page are fragmentary and immature notes/thoughts of the author. Please read with your own judgement!

  1. 很多frequentist的inference是基于大样本(近似)理论的,这种情况下样本小的时候Bayesian结论可能会更好。

  2. 某些统计量实在太复杂,(近似)分布很难推到。而Bayesian分析本质上就是模拟,简单直接有效,除了速度可能会很慢。

  3. 某些问题时就是从Bayesian的框架(一堆conditional distribution conditions)提出的,这种问题就是为Bayesian量身裁衣的。
