bamdit: An R Package for Bayesian Meta-Analysis of Diagnostic Test Data

Journal of Statistical Software, 2018
In this paper we present the R package bamdit. The name of the package stands for "Bayesian meta-analysis of diagnostic test data". bamdit was developed with the aim of simplifying the use of models in meta-analysis, that up to now have demanded great ...

A Novel Approach to Improve the Estimation of a Diet Adherence Considering Seasonality and Short Term Variability – The NU-AGE Mediterranean Diet Experience

Frontiers in Physiology, 2019
In this work we present a novel statistical approach to improve the assessment of the adherence to a 1-year nutritional intervention within the framework of the NU-AGE project. This was measured with a single adherence score based on 7-days food records,

Effects of camera‐trap placement and number on detection of members of a mammalian assemblage

Ecosphere, 2021
A central goal in camera‐trapping (CT) studies is to maximize detection probability and precision of occupancy estimates while minimizing the number of CTs to reduce equipment and labor costs.

Scaling Laws in Hierarchical Clustering Models with Poisson Superposition

, 1994
Properties of cumulant- and combinant ratios are studied for multihadron final states composed of Poisson distributed clusters. The application of these quantities to ``detect'' clusters is discussed.

Morphological variance in cave and surface populations of Asellus aquaticus challenges the fluctuating selection and greater male variability hypotheses

Frontiers in Ecology and Evolution
IntroductionFluctuating selection, the changes in the strength and/or direction of natural selection stemming from fine-scale spatio-temporal environmental variation, is a fundamental, yet rarely tested explanation for the maintenance of phenotypic ...

A review of spatial capture–recapture: Ecological insights, limitations, and prospects

Ecology and Evolution, 2022
First described by Efford (2004), spatial capture–recapture (SCR) has become a popular tool in ecology. Like traditional capture–recapture, SCR methods account for imperfect detection when estimating ecological parameters.

The environmental dependence of clustering in hierarchical models

, 2005
In hierarchical models, density fluctuations on different scales are correlated. This induces correlations between dark halo masses, their formation histories, and their larger-scale environments.
