Functional generalized empirical likelihood estimation for conditional moment restrictions [PDF]

open access: yes, 2022
Important problems in causal inference, economics, and, more generally, robust machine learning can be expressed as conditional moment restrictions, but estimation becomes challenging as it requires solving a continuum of unconditional moment ...

Variable Selection for Generalized Linear Mixed Models by L1-Penalized Estimation [PDF]

open access: yes, 2011
Generalized linear mixed models are a widely used tool for modeling longitudinal data. However, their use is typically restricted to few covariates, because the presence of many predictors yields unstable estimates.

Nonparametric Estimation of the Link Function Including Variable Selection [PDF]

open access: yes, 2010
Nonparametric methods for the estimation of the link function in generalized linear models are able to avoid bias in the regression parameters. But for the estimation of the link typically the full model, which includes all predictors, has been used ...
