Analysis and Discussion on Calculating Likelihood Ratio of DNA Mixture / 法医学杂志

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 from ISFG.@*RESULTS@#The likelihood ratios were maximum by Clayton's method and recommendations from ISFO, followed by result of the unrestricted combinational method. The minimum likelihood ratio was obtained by p2 principle.@*CONCLUSION@#The unrestricted combinational method could give fUrthest consideration to both information preservation and appraiser protection.
