Forensic statistics

From Wikipedia, the free encyclopedia

Forensic statistics is the application of probability models and statistical techniques to scientific evidence, such as DNA evidence,[1] and the law. In contrast to "everyday" statistics, to not engender bias or unduly draw conclusions, forensic statisticians report likelihoods as likelihood ratios (LR). This ratio of probabilities is then used by juries or judges to draw inferences or conclusions and decide legal matters.[1]

Although the precise origin of this term remains unclear, it is apparent that the term was used in the 1980s and 1990s.[2] Among the first forensic statistics conferences were two held in 1991 and 1993.[3]
