Diagnostic information produces better-calibrated judgments about forensic comparison evidence than likelihood ratios.

The distribution of calibrated likelihood-ratios in speaker recognition

This paper studies properties of the score distributions of calibrated log-likelihood-ratios that are used in automatic speaker recognition. We derive the essential condition for calibration that the log likelihood ratio of the log-likelihood-ratio is the log-likelihood-ratio. We then investigate what the consequence of this condition is to the probability density functions (PDFs) of the loglik...

A brief note about likelihood ratios.

In this issue of the journal, Azzam and colleagues review the validation study of a clinical prediction rule for termination of resuscitation in patients suffering an out-of-hospital cardiac arrest. The clinical prediction rule is similar to a diagnostic test in that it predicts whether or not the patient will suffer the disorder of interest, in this case death, before hospital discharge. Given...

Making sense of diagnostic test likelihood ratios.

Likelihood ratios: getting diagnostic testing into perspective.

In modern medicine, sophisticated laboratory tests and imaging studies are often emphasized at the expense of history and physical examination, rather than complementing clinical assessment. Ancillary testing often fails to advance the diagnostic process, and increases patient risk and the expense of medical care. The relative value of clinical evaluation and technological methods is rarely con...
