在法医背景下对 DNA 混合物的解释提出了特殊的挑战。处理这些问题的唯一合乎逻辑的方法是通过贝叶斯推理，在大多数情况下，这会导致制定似然比，权衡有利于两个相互竞争的假设的证据。然而，可能会出现提出额外假设的情况，并且作者讨论了一种这样的情况 - 即混合物的贡献者数量存在争议。提出了一种处理该问题的方法。
The interpretation of mixtures of DNA in the forensic context presents particular challenges. The only logical means available for dealing with them is through Bayesian inference, which leads to the formulation, in most cases, of a likelihood ratio which weighs the evidence in favour of two competing hypotheses. However, situations can arise in which additional hypotheses are proposed and the authors discuss one such situation - that where the number of contributors to the mixture is in dispute. A way of dealing with the problem is presented.
