| 摘 要： | 介绍用Logistic 曲线来计算初潮均龄及95%可信区间,该方法只需原始数据即可进行计算,不必将来潮率以概率单位置换,从而避免了年龄与发生率的S 形曲线与正态分布函数相符这一要求。经验证和比较,认为本方法计算简便,误差小,是一种值得采用的方法。

| Abstract: | The method for calculating mean menarche age by using logistic curve is introduced in this paper.The
method only needs firsthand data.The calculation is simple and error of result is small by verifying practical
data and comparing with other methods.So it is an effective method.This paper also suggests to narrow the
range of ages in dividing the age groups when collecting these statistical data. |
