摘要
本文应用灰色控制系统理论中灰导数拓扑空间的定理和非线性灰色建模的方法,按最小二乘法求解Logistic曲线的参数,成功地建立了女生月经初潮的灰色Logistic模型,并与加权拟合法进行了对比,结果两种拟合方法的差异经F检验,无统计学意义。因灰色建模法计算简单,对样本容量及概率分布没有严格的要求,在月经初潮年龄调查研究中,作为一项新的拟合方法,无疑具有一定的实际意义。
In this paper,the grey-logistic model of girls' menarche was set up,accordinig to the theorems concerned grey control theory founded by Den Julong,and it was compared with the model basing on weighted fitting. The result showed that there was non-statistical difference between two kinds of fitting methods. It was suggested that the grey fitting method could be applied to grey-logistic model of girls' menarche.
