预测胎儿发育的一个多项式回归方程的研究

THE STUDY OF A POLYNOMIAL REGRESSION EQUATION OF PRESUPPOSING FOETUS GROWTH

对B超测得的妊娠100～300日的胎头双顶径(Biparital Dianctoc以下简称BPD),进行多项式回归分析和相关分析,求得了预测胎儿发育的6次多项式回归曲线。

For Biparietal Diameter (i. e. BPD) of pregnanted 100-300 daya foetua deter-mided by B-type ultraaonic, we did polynomial regreaaion analyaia and related analysis, and got 6 order polynomial regreaaion curve of preauppoaing foetua growth.
