Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian tali (24 male and 27 females) and calcanei (26 males and 22 females). Two measurements of the trochlear articular surface of the talus and two measurements of the posterior talar articular surface of the calcaneus were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the single discriminant function derived, accuracy in sex determination was 92.3% and reduction in error over random assignment by sex was 85%.
由于城市化进程加快，在新西兰经常能发现史前波利尼西亚人的骨骼遗骸。由于此类遗骸通常必须迅速重新安葬，因此在相对较短的时间内从遗骸中确定个体性别非常重要。为此，采用判别函数分析来确定史前成年新西兰波利尼西亚人的距骨（24例男性和27例女性）和跟骨（26例男性和22例女性）的性别。对距骨滑车关节面进行了两项测量，对跟骨距骨后关节面进行了两项测量，并将其纳入社会科学统计软件包（SPSS）进行判别函数分析。对于得出的单一判别函数，性别判定的准确率为92.3%，与随机按性别分配相比，误差减少了85%。
