Annotation

As one of the articles in the Virtual Special Issue of Science & Justice entitled, "Measuring and Reporting the Precision of Forensic Likelihood Ratios," the current article argues that given the current state of knowledge, reporting uncertainty in the likelihood ratio is best practice.

Abstract

The author notes, however, that in the future, this practice may be replaced by reporting a Bayes factor, but this is not currently possible except in the simplest of examples. (publisher abstract modified)
