S-estimation for penalized regression splines. [PDF]

open access: yesSSRN Electronic Journal, 2008
This paper is about S-estimation for penalized regression splines. Penalized regression splines are one of the currently most used methods for smoothing noisy data. The estimation method used for fitting such a penalized regression spline model is mostly

Penalized hyperbolic-polynomial splines [PDF]

open access: yesApplied Mathematics Letters, 2021
Splines and spline approximations using penality functions are especially useful tools in univariate approximation theory when univariate data are to be approximated, and when no interpolation property is needed. The methods using piecewise polynomial splines and penalty methods can be formulated via square (or otherwise, other \(L^p\)-norms are ...

Marginal longitudinal semiparametric regression via penalized splines. [PDF]

open access: yesStat Probab Lett, 2010
We study the marginal longitudinal nonparametric regression problem and some of its semiparametric extensions. We point out that, while several elaborate proposals for efficient estimation have been proposed, a relative simple and straightforward one, based on penalized splines, has not. After describing our approach, we then explain how Gibbs sampling

SEMIPARAMETRIC PENALIZED SPLINE REGRESSION [PDF]

open access: yesBulletin of informatics and cybernetics, 2012
In this paper, we propose a new semiparametric regression estimator by using a hybrid technique of a parametric approach and a nonparametric penalized spline method. The overall shape of the true regression function is captured by the parametric part, while its residual is consistently estimated by the nonparametric part.

Dynamic Penalized Splines for Streaming Data

open access: yesStatistica Sinica, 2022
Summary: We propose a dynamic version of the penalized spline regression designed for streaming data that allows for the insertion of new knots dynamically based on sequential updates of the summary statistics. A new theory using direct functional methods rather than the traditional matrix analysis is developed to attain the optimal convergence rate in

Modeling latent spatio-temporal disease incidence using penalized composite link models.

open access: yesPLoS ONE, 2022
Epidemiological data are frequently recorded at coarse spatio-temporal resolutions to protect confidential information or to summarize it in a compact manner.

Bi-Smoothed Functional Independent Component Analysis for EEG Artifact Removal

open access: yesMathematics, 2021
Motivated by mapping adverse artifactual events caused by body movements in electroencephalographic (EEG) signals, we present a functional independent component analysis based on the spectral decomposition of the kurtosis operator of a smoothed principal

Correlated Functional Models with Derivative Information for Modeling Microfading Spectrometry Data on Rock Art Paintings

open access: yesMathematics, 2020
Rock art paintings present high sensitivity to light, and an exhaustive evaluation of the potential color degradation effects is essential for further conservation and preservation actions on these rock art systems.

Semiparametric Additive Beta Regression Models

open access: yesRevstat Statistical Journal, 2021
In this paper, we study a semiparametric additive beta regression model using a parameterization based on the mean and a dispersion parameter. This model is useful for situations where the response variable is continuous and restricted to the unit ...

LASSO type Penalized Spline Regression for Binary Data [PDF]

open access: yesBMC Medical Research Methodology, 2020
Abstract Background: Generalized linear mixed models (GLMMs), typically used for analyzing correlated data, can also be used for smoothing by considering the knot coefficients from a regression spline as random effects. The resulting models are called semiparametric mixed models (SPMMs).
