Improved smoothing spline regression by combining estimates of different smoothness

Author

  • Lee, Thomas C. M.

Abstract

This paper studies nonparametric regression using smoothing splines. It proposes a method that combines smoothing spline estimates of different smoothness to form a final improved estimate. This new method is straightforward to implement, computationally inexpensive, and gives reliable performances in simulations.
