The absence of population-specific standards for sex, age and stature estimation for rural Guatemala is problematic for the forensic analysis of skeletal remains recovered from clandestine graves attributed to the recent armed conflict in that country. In order to increase the reliability of the forensic analyses being undertaken in Guatemala, standards for metric determination of sex were developed. Data was collected on several bones; the results for the humerus are presented here. A sample of 118 complete humeri (68 male and 50 female) was studied; maximum length, maximum diameter of the head, circumference at midshaft, maximum diameter at midshaft, minimum diameter at midshaft and epicondylar breadth were measured and subjected to discriminant function analysis. The classification accuracies for the univariate functions range from 76.8% for the maximum diameter at midshaft to 95.5% for the maximum diameter of the head. The classification accuracy for the stepwise procedure was 98.2%.
危地马拉农村地区缺乏针对性别、年龄和身高估算的特定人群标准，这给从该国近期武装冲突相关秘密坟墓中挖掘出的骨骼遗骸进行法医分析带来了问题。为了提高危地马拉正在进行的法医分析的可靠性，制定了性别度量测定标准。收集了多块骨头的数据；此处展示的是肱骨的结果。研究了118个完整肱骨样本（68个男性和50个女性）；测量了最大长度、头部最大直径、骨干中部周长、骨干中部最大直径、骨干中部最小直径和髁上宽度，并进行判别函数分析。单变量函数的分类准确率从中部最大直径的76.8%到头部最大直径的95.5%不等。逐步程序的分类准确率为98.2%。
