The Bayes factor is a ratio of two competing statistical models represented by their evidence, and is used to quantify the support for one model over the other. The models in questions can have a common set of parameters, such as a null hypothesis and an alternative, but this is not necessary; for instance, it could also be a non-linear model compared to its linear approximation. The Bayes factor can be thought of as a Bayesian analog to the likelihood-ratio test, but since it uses the (in… Web23 de abr. de 2024 · In forensic statistics, the value of evidence is defined as the Bayes Factor (Aitken and Taroni 2004, Good 1991), but often referred to as the likelihood ratio. While statisticians agree that Bayes Factors and likelihood ratios can serve as the value of evidence, statisticians distinguish them as two different statistics, while the two are used …
