Berkson首先把Logistic曲线模型用于实验生物鉴定。郭祖超教授曾提出Logistic曲线模型可用于生长发育资料的分析。近来崔氏等对Logistic曲线应用于月经初潮平均年龄计算作了介绍,本文拟详细介绍月经初潮现况调查资料应用Logistic曲线模型拟合的步骤,并对实用价值进行讨论。 Berkson first used the Logistic curve model for experimental bioassays. Professor Guo Zuchao has proposed that Logistic curve model can be used for analysis of growth and development data. Recently, Cui et al introduced the use of Logistic curve to calculate the average age of menarche. This article will detail the steps of applying the logistic curve model to mensurate the situation of menarche, and discuss the practical value.
