摘要
Abstract
Objective To analyze and discuss four methods of calculating likelihood ratio of DNA mixture. Methods In the case with CNAS-T0757 proficiency testing in 2013, the likelihood ratios were calculated and compared among four methods, including unrestricted combinatorial method, Clayton’s method, p2 principle method, and recommendations fromISFG . Results The likelihood ratios were maximumby Clayton’s method and recommendations fromISFG , followed by result of the unrestricted combinational method. The minimu mlikelihood ratio was obtained by p2 principle. Conclusion The unrestricted combi-national method could give furthest consideration to both information preservation and appraiser protection.关键词
