Youden's Index and the Weight of Evidence

G. Hughes

Abstract

Summary

By means of Shannon’s relationship between information and probability, Youden’s index for rating diagnostic tests is shown to be a probability-scale analogue of the log-likelihood ratio of a positive test outcome.

Keywords

Youden’s index - log-likelihood ratio - Bayes’ theorem - diagnostic test
