Oracally Efficient Two-Step Estimation of Generalized Additive Model [PDF]

Journal of the American Statistical Association, 2011
The generalized additive model (GAM) is a multivariate nonparametric regression tool for non-Gaussian responses including binary and count data. We propose a spline-backfitted kernel (SBK) estimator for the component functions and the constant, which are oracally efficient under weak dependence.

Antioxidative Properties of Functional Polyphenols and Their Metabolites Assessed by an ORAC Assay [PDF]

Bioscience, Biotechnology, and Biochemistry, 2012
We compared the antioxidative activities of polyphenol metabolites with those of intact functional polyphenols by an assay of the oxygen radical absorbance capacity (ORAC). The metabolites of ellagitannin geraniin, chlorogenic acid, and (-)-epigallocatechin gallate displayed more potent antioxidative activity than their respective original compounds ...
