Bootstrapping for penalized spline regression

, 2006
We describe and contrast several different bootstrapping procedures for penalized spline smoothers. The bootstrapping procedures considered are variations on existing methods, developed under two different probabilistic frameworks. Under the first framework, penalized spline regression is considered an estimation technique to find an unknown smooth ...

An algorithm for locally adaptive bivariate penalized splines

Journal of Computational and Applied Mathematics
This paper introduces a penalized spline model for bivariate smoothing that locally adjusts to gridded data set affected by noise varying across different areas of the domain. As for all penalized spline methods, the approach requires the definition of suitable penalty terms and the selection of the regularization parameters.

Monitoring wildlife health for diseases with visible signs by integrating camera traps with marked individuals

Conservation Biology, EarlyView.
Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To

Spline Estimator in Multi-Response Nonparametric Regression Model

Jurnal Ilmu Dasar, 2010
In many applications two or more dependent variables are observed at several values of the independent variables, such as at time points. The statistical problems are to estimate functions that model their dependences on the independent variables, and to

Modifiable dementia risk factors and AT(N) biomarkers: findings from the EPAD cohort

Frontiers in Aging Neuroscience
IntroductionModifiable risk factors account for a substantial proportion of Alzheimer’s disease (AD) cases and we currently have a discrete AT(N) biomarker profile for AD biomarkers: amyloid (A), p-tau (T), and neurodegeneration (N).

Proteomic Profiling Captures Residual Cardiovascular Risk Beyond the PREVENT Model in Individuals With Cardiovascular–Kidney–Metabolic Syndrome Stages 2–3

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Background Cardiovascular–kidney–metabolic (CKM) syndrome reflects complex pathobiological interactions among metabolic disorders, kidney injury, and cardiovascular disease (CVD). Stages 2 and 3 represent critical phases of disease progression characterised by high pathological heterogeneity.

Computationally Efficient Ranking of Sampling Locations by Redundancy in Groundwater Monitoring Networks

Groundwater Monitoring &Remediation, EarlyView.
Abstract The long‐term and frequent sampling of groundwater monitoring networks is common practice for monitoring the concentrations of constituents of potential concern (CoPC) over space and time. Sampling can be a costly and time‐intensive process that also incurs health and safety risks. A redundancy‐based ranking of candidate sampling locations can

Reference percentiles for mid-upper arm circumference, upper arm muscle and fat areas of Nigerian children and adolescent population aged 0 – 19 years

Rwanda Medical Journal
INTRODUCTION: Mid-upper arm circumference (MUAC) has commonly been used for many years as an alternative nutritional status index in field settings, yet estimates of percentile range for healthy children and adolescents have not been documented in ...

Predicting habitat suitability of selected Meloidae species and future potential refugia: A case study from inner Western Anatolia

Insect Conservation and Diversity, EarlyView.
Consensus habitat‐suitability maps identify current hotspots of species richness across the Inner Western Anatolian mountain systems. Late‐century projections (2081–2100) under SSP2‐4.5 and SSP5‐8.5 show range shifts and changing richness patterns, intensifying at higher elevations.

The Decentralization of Liquor Policies in Texas During the Post‐Prohibition Era

International Economic Review, EarlyView.
ABSTRACT We examine the decentralization of liquor policies in Texas during the Post‐Prohibition era using newly collected historical legislative roll call data. By combining these data with local referendum vote shares, we analyze both legislators' and constituents' preferences on liquor policy.
