基于惩罚回归样条的函数导数拟合
Fitting Derivative Function Based on Penalized Regression Spline
摘要
Abstract
When the function is not identified but its discrete data points are given , fitting function based on penalized spline with pth-degree truncated power basis is constructed, and the first derivative of function is given.The method combines classical ordinary least squares and penalized spline smoothing , both the goodness and the smoothness of fitting curve are considered , simu-lations and application show its good efficiency .关键词
