Statistics in forensic science

Authors


Abstract

Statistical thinking and computation are taking an increasing role in the field of forensic science. Heavy emphasis on Bayesian reasoning and logic over the last 20 years has revolutionized the interpretation of DNA evidence, glass evidence, and fingerprint evidence. This revolution has led to an increased demand for statistical software that makes the methodology accessible and usable. Interpretation of evidence is one part of forensic science where statistics is making a contribution. There are strong efforts, especially in the field of DNA, being made toward developing probabilistic expert systems which can aid investigators through intelligence-led policing. This paper will attempt to review the advances that have been made in the field of forensic science through statistical methodology. Copyright © 2009 John Wiley & Sons, Inc.
