Abstract:
|
We start with a review of the measurement-error-model based variable selection framework proposed by Stefanski, Wu and White (2012), measurement error shrinkage and selection operator (MESSO). The approach is then applied to derive variable selection methods for nonparametric regression. The resulting estimator is shown to be related to kernel-based nonparametric regression estimators. The selection feature of the new method is described in detail. Performance of the new method is studied via a combination of asymptotics, Monte Carlo simulation, and applications to real data sets.
