本文运用多元线性回归分析的方法,对74例成人汉族男性胸骨(19～48岁)的形态变化与年龄的关系进行了研究。通过胸骨上选定的7个形态变化标志点,依其各自的形态变化规律,制定出相应的等级评分标准。根据此标准对74例胸骨标本进行了观察评分。然后将所得原始数据和年龄一起输入电子计算机,求出由胸骨形态变化,计算年龄的多元回归方程: =10.78+0.82X_1+0.85X_2+0.80X_3+0.38X_4+2.51X_5+0.64X_6+3.02X_7±2.45 经方差分析表明P<0.01,回归高度显著。本文提出的胸骨判定年龄的方法,在无名尸骨的法医学鉴定中,具有实用价值。
In this study, we used multivariate linear regression analysis to study the relationship between the age-related changes in the sternum (19- to 48-year-old) in 74 adult Han Chinese men. Through the sternum on the selected seven signs of morphological changes, according to their respective morphological changes, develop the corresponding level grading standards. According to this standard, 74 cases of sternum specimens were observed and scored. Then, the obtained raw data were input into a computer together with the age, and the multiple regression equation for calculating the age by the change of sternum morphology was obtained: = 10.78 + 0.82X_1 + 0.85X_2 + 0.80X_3 + 0.38X_4 + 2.51X_5 + 0.64X_6 + 3.02X_7 ± 2.45 Analysis of variance showed that P <0.01, the regression height was significant. The proposed method for determining the age of the sternum has practical value in forensic identification of anonymous bones.
