Generalized Additive Models with Unknown Link Function Including Variable Selection [PDF]

open access: yes, 2013
The generalized additive model is a well established and strong tool that allows to model smooth effects of predictors on the response. However, if the link function, which is typically chosen as the canonical link, is misspecified, substantial bias is ...

Nonparametric estimation of an additive quantile regression model [PDF]

open access: yes, 2004
This paper is concerned with estimating the additive components of a nonparametric additive quantile regression model. We develop an estimator that is asymptotically normally distributed with a rate of convergence in probability of n^{-r/(2+10)} when ...
