2009 journal article

Automatic model selection for partially linear models

JOURNAL OF MULTIVARIATE ANALYSIS, 100(9), 2100–2111.

By: X. Ni n, H. Zhang n & D. Zhang n

author keywords: Semiparametric regression; Smoothing splines; Smoothly clipped absolute deviation; Variable selection
TL;DR: A new type of double-penalized least squares is formulated, using the smoothing spline to estimate the nonparametric part and applying a shrinkage penalty on parametric components to achieve model parsimony. (via Semantic Scholar)

2009 journal article

Variable Selection for Semiparametric Mixed Models in Longitudinal Studies

BIOMETRICS, 66(1), 79–88.

By: X. Ni*, D. Zhang n & H. Zhang n

author keywords: Correlated data; Gaussian stochastic process; Linear mixed models; Smoothly clipped absolute deviation; Smoothing splines
MeSH headings : Algorithms; Bayes Theorem; Biometry / methods; Computer Simulation; Data Interpretation, Statistical; Epidemiologic Methods; Information Storage and Retrieval / methods; Longitudinal Studies; Models, Statistical
TL;DR: A double-penalized likelihood approach for simultaneous model selection and estimation in semiparametric mixed models for longitudinal data, which provides valid inference for data with missing at random and will be more efficient if the specified model is correct. (via Semantic Scholar)
