A scale of interpretation for likelihood ratios and Bayes factors

Methodology 2024-03-01 v3

Abstract

Several subjective proposals have been made for interpreting the strength of evidence in likelihood ratios and Bayes factors. I identify a more objective scaling by modelling the effect of evidence on belief. The resulting scale with base 3.73 aligns with previous proposals and may partly explain intuitions.
