survHE: Survival Analysis for Health Economic Evaluation and Cost-Effectiveness Modeling

open access: yesJournal of Statistical Software, 2020
Survival analysis features heavily as an important part of health economic evaluation, an increasingly important component of medical research. In this setting, it is important to estimate the mean time to the survival endpoint using limited information (

Comparison of inference methods of genetic parameters with an application to body weight in broilers [PDF]

open access: yesArchives Animal Breeding, 2015
REML (restricted maximum likelihood) has become the standard method of variance component estimation in animal breeding. Inference in Bayesian animal models is typically based upon Markov chain Monte Carlo (MCMC) methods, which are generally flexible but

Estimating the Expected Value of Partial Perfect Information in Health Economic Evaluations using Integrated Nested Laplace Approximation [PDF]

open access: yes, 2016
The Expected Value of Perfect Partial Information (EVPPI) is a decision-theoretic measure of the "cost" of parametric uncertainty in decision making used principally in health economic decision making.

A spliced Gamma-Generalized Pareto model for short-term extreme wind speed probabilistic forecasting [PDF]

open access: yes, 2019
Renewable sources of energy such as wind power have become a sustainable alternative to fossil fuel-based energy. However, the uncertainty and fluctuation of the wind speed derived from its intermittent nature bring a great threat to the wind power ...

A general theory for preferential sampling in environmental networks

open access: yes, 2019
This paper presents a general model framework for detecting the preferential sampling of environmental monitors recording an environmental process across space and/or time.

Spatio-Temporal Modeling for Forecasting High-Risk Freshwater Cyanobacterial Harmful Algal Blooms in Florida

open access: yesFrontiers in Environmental Science, 2020
Due to the occurrence of more frequent and widespread toxic cyanobacteria events, the ability to predict freshwater cyanobacteria harmful algal blooms (cyanoHAB) is of critical importance for the management of drinking and recreational waters.

Bayesian spatial modelling of contraception effects on fertility in Mexican municipalities in 2020

open access: yesGeospatial Health, 2022
The prevalence and use of contraceptive methods is an essential element to explain the behaviour of fertility and population growth. The objective of this study was to analyse the spatial correlation between the use of contraceptive methods in women of ...

A note on intrinsic Conditional Autoregressive models for disconnected graphs

open access: yes, 2017
In this note we discuss (Gaussian) intrinsic conditional autoregressive (CAR) models for disconnected graphs, with the aim of providing practical guidelines for how these models should be defined, scaled and implemented. We show how these suggestions can

Computer model calibration with large non-stationary spatial outputs: application to the calibration of a climate model [PDF]

open access: yes, 2018
Bayesian calibration of computer models tunes unknown input parameters by comparing outputs with observations. For model outputs that are distributed over space, this becomes computationally expensive because of the output size.

Analysis of childhood overweight and obesity in Namibia using spatio-temporal quantile interval models

open access: yesJournal of Health, Population and Nutrition, 2021
The global prevalence of overweight (including obesity) in children under 5 years of age was 7% in 2012, and it is expected to rise to 11% by the year 2025.
