Title: Extensions of Penalized Spline Regression for Natural Resource Monitoring Applications
Author(s): Jay Breidt*+
Companies: Colorado State University
Address: 201 Statistics, Fort Collins, CO, 80523-1877,
Keywords: nonparametric regression ; environmental statistics ; small area estimation
Abstract:

Penalized splines have a number of useful features that make them ideally suited for application in natural resource monitoring. They complement standard linear mixed modeling by flexibly describing nonlinear features in a fairly automatic way. They are easily implemented in standard statistical software and are readily extended to novel application contexts. Two examples illustrate this flexibility and extensibility: small area estimation of soil profiles and spatial smoothing on stream networks.
