Deborah Mayo on using Frequentist p values as pseudoBayes

2019 December 19

Deborah Mayo considers using “p-values as a kind of likelihood in a quasi-Bayesian computation” as an “erroneous interpretation” of the meaning of Frequentist statistics.

My assertion is that among people doing more than just a couple t tests, particularly among people using Random Effects or Mixed Effects models, they are *already* doing a shabby sort of Bayesian modeling without taking responsibility for including real useful prior information, or doing appropriate model checking etc. It’s time to recognize that “Bayes with a flat prior and a linear predictor function” is not “Objective, Frequentist Statistics” it’s low grade passive Bayes.
