摘要
以某市2011-2015年城市、城镇和乡村育龄妇女生育率为例,建立生育率随年龄、时间变化模型,借助Béizer基函数,利用有理曲线代替多项式曲线对数据进行拟合。给出全国育龄妇女生育率随时间变化模型,用数据说明有理曲线较多项式曲线拟合度更为优良。
Taking the fertility rate of women of childbearing age in cities,towns and villages in a city from 2011 to 2015 as an example,the fertility rate was established with the age and time variation model.The Béizer basis function was used to fit the polynomial curve with rational curve instead of the polynomial curve.Giving the model of fertility of women of childbearing age over time,using the data to illustrate the rational curve is more excellent than polynomial curve.
