Non-Parametric Small Area Estimation Using Penalized Spline Regression [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2005 SummaryThe paper proposes a small area estimation approach that combines small area random effects with a smooth, non-parametrically specified trend. By using penalized splines as the representation for the non-parametric trend, it is possible to express the non-parametric small area estimation problem as a mixed effect model regression.

M-type penalized splines with auxiliary scale estimation [PDF]
Journal of Statistical Planning and Inference, 2021 Penalized spline smoothing is a popular and flexible method of obtaining estimates in nonparametric regression but the classical least-squares criterion is highly susceptible to model deviations and atypical observations. Penalized spline estimation with a resistant loss function is a natural remedy, yet to this day the asymptotic properties of M-type ...

Continuous Ordinal Regression for Analysis of Visual Analogue Scales: The R Package ordinalCont
Journal of Statistical Software, 2020 This paper introduces the R package ordinalCont, which implements an ordinal regression framework for response variables which are recorded on a visual analogue scale (VAS). This scale is used when recording subjects' perception of an intangible quantity

Spline-based self-controlled case series method [PDF]
, 2017 The self-controlled case series (SCCS) method is an alternative to study designs such as cohort and case control methods and is used to investigate potential associations between the timing of vaccine or other drug exposures and adverse events.

Parametrization and penalties in spline models with an application to survival analysis [PDF]
, 2008 In this paper we show how a simple parametrization, built from the definition of cubic splines, can aid in the implementation and interpretation of penalized spline models, whatever configuration of knots we choose to use.

Variable Selection and Model Choice in Geoadditive Regression Models [PDF]
, 2007 Model choice and variable selection are issues of major concern in practical regression analyses. We propose a boosting procedure that facilitates both tasks in a class of complex geoadditive regression models comprising spatial effects, nonparametric ...

A time series analysis of meteorological factors and hospital outpatient admissions for cardiovascular disease in the Northern district of Guizhou Province, China [PDF]
Brazilian Journal of Medical and Biological Research, 2014 Findings on the effects of weather on health, especially the effects of ambient temperature on overall morbidity, remain inconsistent. We conducted a time series study to examine the acute effects of meteorological factors (mainly air temperature) on ...
