预测胎儿发育的一个多项式回归方程的研究

THE STUDY OF A POLYNOMIAL REGRESSI ON EQUATION OF PRESUPPOSING FOETUS GROWTH

对Ｂ超测得的妊娠１００—３００日的胎头双顶径（ＢｉｐａｒｉｔａｌＤｉａｎｃｔｏｃ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 Biperietal baitter (i.e. BPD) d Pregnanted 100-300 days foetus determined by B-type ultrasonic,we did polynomial regression analysis and related analysis, and got 6 order wiynondal regression curse d presuppeing foetus growth.
