儿童生长曲线的光滑样条和核估计拟合

Smoothing Spline and Kernel Estimators in Fitting Childhood Growth Curves.

本文讨论了用非参数模型对儿童生长曲线进行拟合，给出了两种非参数曲线拟合方法：光滑样条和核估计。文中结合实例，构建了儿童体重的非参数百分位数曲线。

This paper discusses childhood growth curve fitting by nonparametric models, and provides two methods for nonparametric curve fitting: smoothing spline and kernel estimator. The percentile curves of childhood weight are constrcted,along with an example.
