Abstract

Scott & Rogers (2026) https://doi.org/10.1016/j.forsciint.2025.112673 promotes the use of the likelihood-ratio framework in forensic anthropology. This is welcome. Unfortunately, Scott & Rogers (2026) uses an incorrect formula for the calculation of likelihood ratios. This incorrect formula did not originate in Scott & Rogers (2026). It has, for some time, been used in the forensic anthropology literature; an earlier occurrence appears in Steadman et al. (2006) https://doi.org/10.1002/ajpa.20393. Scott & Rogers (2026) also uses confusing language and mathematical notation that are non-standard compared to the norms of the forensic-inference-and-statistics literature. This letter to the editor is offered in the hope that it will help prevent repetition of these problems.

法医人类学中使用的似然比计算公式不正确：对斯科特和罗杰斯（2026）的评论。

Scott & Rogers (2026) https://doi.org/10.1016/j.forsciint.2025.112673提倡在法医人类学中使用似然比框架。这是受欢迎的。不幸的是，Scott & Rogers（2026）使用了一个不正确的公式来计算似然比。这个错误的公式并不是起源于Scott & Rogers（2026）。一段时间以来，它一直被用于法医人类学文献；Steadman et al. (2006) https://doi.org/10.1002/ajpa.20393中出现了更早的情况。斯科特和罗杰斯（2026）也使用了令人困惑的语言和数学符号，与法医推理和统计文献的规范相比，这些符号是非标准的。这封给编辑的信是希望它能帮助防止这些问题的再次发生。
