Comments on Divergence vs. Decision P -values: A Distinction Worth Making in Theory and Keeping in Practice - or, How Divergence P-values Measure Evidence Even When Decision P-values Do Not by Greenland in Scandinavian Journal of Statistics , 2023.

摘要

Greenland (2023) distinguishes between P-values used for data description and P-values used for declaring significance. That's a useful distinction and Greenland has advanced our field by making it. That distinction comes with the idea that describing data with statistical models is often a useful task for statisticians. Again, we agree. Along the way, Greenland also says (i) there is such a thing as a "measure horizontal ellipsis of evidence from data against a statistical hypothesis or model" without regard to alternatives; (ii) "a discrepancy P-value is an ordinal description horizontal ellipsis "; (iii) descriptive "P-values can be derived to provide coherent measures of refutational evidence"; and a few other things that deserve comment and discussion.
