Springer Smoothing Spline ANOVA Models: 297 (Springer Series in Statistics, 297)

Updated to include the latest computational methods, this second edition explains how to use the ‘gss’ R package and features expanded empirical studies, a reorganized content, and a further new appendix analyzing new and controversial topics in smoothing. Review “The purpose of the book is to comprehensively present smoothing and penalized splines from the point of view of reproducing kernel Hilbert spaces (RKHS). … the book makes a valuable contribution to the literature on smoothing and penalized splines, especially for more mathematically oriented researchers.” (W. John Braun, Technometrics, Vol. 56 (4), November, 2014) From the Back Cover Nonparametric function estimation with stochastic data, otherwise known as smoothing, has been studied by several generations of statisticians. Assisted by the ample computing power in today's servers, desktops, and laptops, smoothing methods have been finding their ways into everyday data analysis by practitioners. While scores of methods have proved successful for univariate smoothing, ones practical in multivariate settings number far less. Smoothing spline ANOVA models are a versatile family of smoothing methods derived through roughness penalties, that are suitable for both univariate and multivariate problems. In this book, the author presents a treatise on penalty smoothing under a unified framework. Methods are developed for (i) regression with Gaussian and non-Gaussian responses as well as with censored lifetime data; (ii) density and conditional density estimation under a variety of sampling schemes; and (iii) hazard rate estimation with censored life time data and covariates. The unifying themes are the general penalized likelihood method and the construction of multivariate models with built-in ANOVA decompositions. Extensive discussions are devoted to model construction, smoothing parameter selection, computation, and asymptotic convergence.
