  • Cybergenetics :: Explaining the Likelihood Ratio in DNA Mixture Interpretation
    logarithm is a standard information measure for stating the support for a simple hypothesis i e a single assertion relative to its logical alternative After Alan Turing s LR methods cracked the German Enigma code during World War II LR usage became widespread The LR is ubiquitous in the physical biological social economic computer and forensic sciences First introduced into biological identification through paternity testing the LR enjoys unparalleled international usage as the most informative DNA mixture statistic Yet American crime labs avoid the LR and prefer to report DNA inclusion statistics that they find easier to explain in court Such inclusion methods variously termed PI CPI CPE or RMNE use less of the DNA data typically discarding a million fold factor of identification information Thus highly informative DNA mixture evidence can be reported as inconclusive or assigned an unrealistically low match score Unfortunately minimizing DNA evidence leads to a failure to identify criminals with an adverse effect on public safety To make the LR more acceptable to American analysts and their juries we need more intuitive ways to explain the LR Fortunately the LR can be expressed by Bayes theorem in several equivalent ways Stated in plain English these

  • Cybergenetics :: Validating TrueAllele DNA mixture interpretation
    1430 47 2011 Downloads Download Full Manuscript Full Article Published in JFS cannot be copied or reprinted without permission of JFS Abstract DNA mixtures with two or more contributors are a prevalent form of biological evidence Mixture interpretation is complicated by the possibility of different genotype combinations that can explain the short tandem repeat STR data Current human review simplifies this interpretation by applying thresholds to qualitatively treat STR data peaks as all or none events and assigning allele pairs equal likelihood Computer review however can work instead with all the quantitative data to preserve more identification information The present study examined the extent to which quantitative computer interpretation could elicit more identification information than human review from the same adjudicated two person mixture data The base ten logarithm of a DNA match statistic is a standard information measure that permits such a comparison On eight mixtures having two unknown contributors we found that quantitative computer interpretation gave an average information increase of 6 24 log units min 2 32 max 10 49 over qualitative human review On eight other mixtures with a known victim reference and one unknown contributor quantitative interpretation averaged a 4 67 log factor increase min
