| 摘 要： | 本文对202例胎儿测量的数据进行了多元线性回归分析和逐步回归分析,包括胎儿身长(x_1),顶臀长(x_2)、枕额径(x_3)、双顶径(x_4)、头围(x_5)、胸围(x_6)、腹围(x_7)和体重(x_8)等八个自变量与应变量胎龄(y)的关系,即:y=b_0十b_1x_1+b_2x_2+b_3x_3+b_4x_4+b_5x_5+b_6x_6+b_7x_7+b_8x_8的多元回归方程。结果各项指标均与胎龄有明显的相关性,其中x_1、x_3、x_5、x_6、x_7、x_8与胎龄的相关性最大。

| Abstract: | The data of 202 foetuses are analysed by pluralistic linear regression and progressive regression in this paper.Independent variable consists of foesus length(X_1),crown-buttock length(X_2), occipitofrontal diameter(X_3),parieto-parietal diameter(X_4), circumference of head(X_5),circumference of breast(X_6), circumference of abdomen(X_7)and body weight(X_8).We have analysed the relationship between all independent variables and fertilization month-age of foetus,dependent variable(Y).We get a pluralistic regression equation,i.e.Y=b_0+b_1x_1+b_2x_2+b_3x_3+b_4x_4 b_5x_5+b_6x_6+b_7x_7+b_8x_8.The results show that there are patent orrelatives between all independent variables and fertilization month- age of foetus.Of them,correlative coefficients are largest between X_1,X_3,X_5,X_6,X_7,X_8 and fertilization month-age of foetus. |
