Many researchers in the field of forensic odontology have questioned the error estimates stated in Gustafson's paper outlining the relationship between certain dental attributes and age. In a substantial re-working of Gustafson's data, Maples and Rice corrected Gustafson's regression statistics and found that the error associated with the age estimate was nearly double that claimed by Gustafson. We offer another statistical analysis of Gustafson's data and find that the errors calculated by Maples and Rice were also in error, being about a year too small. We give a formula for what we believe to be the correct treatment of errors in such cases, but conclude by observing that there is an urgent need for a more rigorous study of the traits first tabulated by Gustafson.
许多法医牙科学领域的研究人员对古斯塔夫森论文中所述的误差估计提出了质疑，该论文概述了某些牙齿特征与年龄之间的关系。在对古斯塔夫森的数据进行大量重新处理时，梅普尔斯和赖斯修正了古斯塔夫森的回归统计数据，发现与年龄估计相关的误差几乎是古斯塔夫森所声称的两倍。我们对古斯塔夫森的数据进行了另一项统计分析，发现梅普尔斯和赖斯计算出的误差也是错误的，小了大约一年。我们给出了一个公式，用于处理我们认为在此类情况下正确的误差，但最后指出，迫切需要对古斯塔夫森首次列出的特征进行更严格的研究。
