Bayes factors can be interpreted continuously so that a Bayes factor of 30 indicates that there is 30 times more support in the data for a given hypothesis than the alternative.

More to the point, the other two Bayes factors are both less than 1, indicating that they’re all worse than that model. The Bayes factors of 0.06 to 1 imply that the odds for the best model over the second best model are about 16:1.

WebIntroduced by Harold Jeffreys, a 'Bayes factor' is a Bayesian alternative to frequentist hypothesis testing that is most often used for the comparison of multiple models by hypothesis testing, usually to determine which model better fits the data (Jeffreys, 1961).
