国人髋臼性别判别分析

Sexual Discriminant Analysis of the Acetabulum

目的 :建立国人髋臼测量的性别判别分析函数。方法 :选用由长春及通辽地区出土的成套成人髋骨 175副 (男 91、女 84 )对其髋臼进行测量 ,并计算出 3个指数值。结果 :应用Fisher判别分析 ,建立了 7个判别函数式 ,其判别符合率 ,男性分别为 93 4 1%、 91 2 1%、92 3 1% ,女性均为 80 95 % ;各个因素中髋臼前后径贡献率最高为 5 6 92 5 %。结论 :对髋臼的性别差异只有通过判别函数式来进行判别 。

Objective:To establish functions sexual discriminant analysis of the acetabulum.Methods:The acetabulum was measured on 175(males 91,females 84)sets of adult hip bones unearthed in Chang Chun and Tong Liao region in Northease China,and three indexes were figured out.Results:The correlative factors were analyesd by Fisher discriminant analysis,seven discriminant Functions of acetabulum were established;the rate for correct discrimination is 80 95% in female and 93 41%,91 21%,92 31% in male respectively;the highest rate of contribute of x 1among all the factors is 56 925%.Conclusion:Sexual discriminant of acetabulum can only be useful when it is determined by means of functions.
