An intriguing example ("outlying posterior phenomenon" -- now named "discrepant posterior phenomenon")

Posterior is more extreme than both the prior and the likelihood! <<<<< Is it a paradox or something else?

1. Combination of p-values

•      Fisher's method
•      Stouffer (normal) method
•      Tippett (min) method
•      Max method
•      Sum method

2. Model based meta-analysis method

•      Fixed-effect model
•      Random-effect model
•      Robust method1 (a small number of large studies)
•      Robust method2 (a large number of small studies)

3. Combine evidence from 2x2 tables

•      Mantel-Haenszelmethod  (odd ratio) (see supplementary notes)
•      Peto's method (log odd ratio) (see supplementary notes)
•      Exact method1 (odd ratio) - ref. Liu et al (Manuscript)
