If you leave it, you lose it: Managing human–wildlife feeding interactions requires constant attention, interdisciplinary approaches and long‐term monitoring

open access: yesPeople and Nature, EarlyView.
Abstract Human–wildlife interactions are becoming more common as we progress through the Anthropocene. People tend to feed wildlife more regularly as it is often popularised by social media and can counteract their disconnect from the natural world. These interactions impact wildlife behaviour, feeding ecology and zoonotic transmission dynamics. Due to

Birnbaum-Saunders Semi-Parametric Additive Modeling

open access: yesRevstat Statistical Journal
Inclusion of nonparametric functions enhances the modeling when accommodating non-linear effects of covariates. Semi-parametric models have been successfully used for describing non-linear structures by means of parametric and nonparametric components ...

Smooth-car mixed models for spatial count data [PDF]

open access: yes
Penalized splines (P-splines) and individual random effects are used for the analysis of spatial count data. P-splines are represented as mixed models to give a unified approach to the model estimation procedure.

Piecewise linear regularized solution paths

open access: yes, 2007
We consider the generic regularized optimization problem $\hat{\mathsf{\beta}}(\lambda)=\arg \min_{\beta}L({\sf{y}},X{\sf{\beta}})+\lambda J({\sf{\beta}})$. Efron, Hastie, Johnstone and Tibshirani [Ann. Statist.

Vector Field‐Based Collision‐Free Navigation in Tunnel‐Like Environments

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Tunnel‐like environments, renowned for their vast scale, confined spaces, and limited visibility, present significant challenges for autonomous robot navigation. This study addresses the critical issue of guiding robots through such environments while ensuring collision‐free navigation and maintaining a specified safety margin from both tunnel

New approaches to regression in financial mathematics and life sciences by generalized additive models

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2008
This paper introduces into and improves the theoretical research done by the authors in the last two years in the applied area of GAMs (generalized additive models) which belong to the modern statistical learning, important in many areas of prediction, e.

Well-Being over the Life Span: Semiparametric Evidence from British and German Longitudinal Data [PDF]

open access: yes
This paper applies semiparametric regression models using penalized splines to investigate the profile of well-being over the life span. Splines have the advantage that they do not require a priori assumptions about the form of the curve. Using data from

P-spline anova-type interaction models for spatio-temporal smoothing [PDF]

open access: yes, 2009
In recent years, spatial and spatio-temporal modelling have become an important area of research in many fields (epidemiology, environmental studies, disease mapping, ...).

Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

Bayesian Analysis for Penalized Spline Regression Using Win BUGS [PDF]

open access: yes, 2007
Penalized splines can be viewed as BLUPs in a mixed model framework, which allows the use of mixed model software for smoothing. Thus, software originally developed for Bayesian analysis of mixed models can be used for penalized spline regression ...
