摘要
本文介绍了似然比(Likelihood Ratios,LR)如何能够用以衡量司法鉴定学证据的强度。解释了为什么司法鉴定界专家不能回答诸如"这是谁干的?"这样的终极问题,但可以给出证据强度的度量值。文章随后描述了近来开发的LR分析模型的概况,包括迄今尚未彻底解决的问题。
This paper describes how Likelihood Ratios (LRs) can be used to measure the strength of evidence in forensic science. It explains why forensic experts cannot answer ultimate questions such as: "Who did it?", but can instead provide measures of the strength of evidence. This is followed by a short state of the art overview of currently developed LR models including a description of problems that are not yet completely solved.
