Discriminant function analysis has been applied to numerous dimensions of the cranial and postcranial skeleton for sex determination of U.S. blacks and whites and is extended here to five measurements of the arm and wrist. These include maximum lengths of the long arm bones in addition to two measurements that reflect wrist breadth. Our results indicate that whites are more accurately classified than blacks, but seven of the 31 possible measurement combinations common to both groups yield functions with sex prediction accuracies comparable to most, but not all, functions based on other parts of the skeleton.
判别函数分析已应用于颅部和颅后骨骼的多个维度，用于美国黑人和白人的性别判定，在此将其扩展到手臂和手腕的五项测量。这些测量除了两项反映手腕宽度的指标外，还包括长臂骨的最大长度。我们的结果表明，白人比黑人的分类更准确，但两组共有的31种可能测量组合中的七种所产生的函数，其性别预测准确率与基于骨骼其他部位的大多数（但不是全部）函数相当。
