Direct Determination of Smoothing Parameter for Penalized Spline Regression

open access: yesJournal of Probability and Statistics, 2014
Penalized spline estimator is one of the useful smoothing methods. To construct the estimator, having goodness of fit and smoothness, the smoothing parameter should be appropriately selected. The purpose of this paper is to select the smoothing parameter

‘Asymptotic properties of penalized spline estimators’

open access: yesBiometrika, 2009
We study the class of penalized spline estimators, which enjoy similarities to both regression splines, without penalty and with fewer knots than data points, and smoothing splines, with knots equal to the data points and a penalty controlling the roughness of the fit.

Bootstrapping for Penalized Spline Regression [PDF]

open access: yesJournal of Computational and Graphical Statistics, 2009
We describe and contrast several different bootstrap procedures for penalized spline smoothers. The bootstrap methods considered are variations on existing methods, developed under two different probabilistic frameworks. Under the first framework, penalized spline regression is considered as an estimation technique to find an unknown smooth function ...

A Semiparametric Sequential Ordinal Model with Applications to Analyse First Birth Intervals

open access: yesAustrian Journal of Statistics, 2016
A semiparametric sequential ordinal model is proposed to analyze socio-demographic and spatial determinants of first birth intervals after marriage. Random effects are introduced to capture spatially structured and unstructured latent covariates.

The Classification of Profiles of Financial Catastrophe Caused by Out-of-Pocket Payments: A Methodological Approach

open access: yesMathematics, 2021
The financial catastrophe resulting from the out-of-pocket payments necessary to access and use healthcare systems has been widely studied in the literature. The aim of this work is to predict the impact of the financial catastrophe a household will face

Application of Penalized Splines in Analyzing Neuronal Data [PDF]

open access: yesBiometrical Journal, 2009
AbstractNeuron experiments produce high‐dimensional data structures. Therefore, application of smoothing techniques in the analysis of neuronal data from electrophysiological experiments has received considerable attention of late. We investigate the use of penalized splines in the analysis of neuronal data. This is first illustrated when interested in

Intensity estimation on geometric networks with penalized splines

open access: yesThe Annals of Applied Statistics, 2022
In the past decades, the growing amount of network data has lead to many novel statistical models. In this paper we consider so called geometric networks. Typical examples are road networks or other infrastructure networks. But also the neurons or the blood vessels in a human body can be interpreted as a geometric network embedded in a three ...
