下肢长骨的性别判别分析研究

本文对在长春地区收集的下肢骨进行了37项线性测量，统计分析显示，所有项目性别差异显著，采用单项指标性别鉴定可以获得较好的效果，其中一些肢骨两端项目性别鉴定价值优于长度项目，本文采用Fisher判别分析方法和逐步判别分析方法建立了多项下肢骨性别判函数，可用于鉴定国人下肢骨性别，判别率可最高达96.3%。

SEX DISCRIMINANT ANALYSIS OF LONG BONES OF LOWER LIMB

37 measurements of bones of lower limb collected in Changchun of Northeastern China were taken. Statistical analysis shows that all measurements have significant sex differences. Good result can be obtained by using single measurement for sexing. Some measurements at both ends of limb bones have better value for sex determination than measurements of length. Several sex discriminant functions of bones of lower limb were established by means of Fisher's method and stepwise discriminant analysis. These discriminant functions can be used to sex Chinese bones of lower limb with highest discriminant rate 96.3%.
