Incorporating Biotic Information in Species Distribution Models: A Coregionalized Approach

open access: yesMathematics, 2021
In this work, we discuss the use of a methodological approach for modelling spatial relationships among species by means of a Bayesian spatial coregionalized model.

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.

Parallelized integrated nested Laplace approximations for fast Bayesian inference

open access: yesStatistics and Computing, 2022
There is a growing demand for performing larger-scale Bayesian inference tasks, arising from greater data availability and higher-dimensional model parameter spaces. In this work we present parallelization strategies for the methodology of integrated nested Laplace approximations (INLA), a popular framework for performing approximate Bayesian inference

Bayesian Analysis of Population Health Data

open access: yesMathematics, 2021
The analysis of population-wide datasets can provide insight on the health status of large populations so that public health officials can make data-driven decisions. The analysis of such datasets often requires highly parameterized models with different

INLA or MCMC? A Tutorial and Comparative Evaluation for Spatial Prediction in log-Gaussian Cox Processes [PDF]

open access: yes, 2012
We investigate two options for performing Bayesian inference on spatial log-Gaussian Cox processes assuming a spatially continuous latent field: Markov chain Monte Carlo (MCMC) and the integrated nested Laplace approximation (INLA). We first describe the

Bayesian Computing with INLA: A Review [PDF]

open access: yes, 2016
The key operation in Bayesian inference is to compute high-dimensional integrals. An old approximate technique is the Laplace method or approximation, which dates back to Pierre-Simon Laplace (1774).

EpiMix: A novel method to estimate effective reproduction number

open access: yesInfectious Disease Modelling, 2023
Transmission potential of a pathogen, often quantified by the time-varying reproduction number Rt, provides the current pace of infection for a disease and indicates whether an emerging epidemic is under control. In this study, we proposed a novel method,

Efficient Reconstructions of Common Era Climate via Integrated Nested Laplace Approximations [PDF]

open access: yesJournal of Agricultural, Biological and Environmental Statistics, 2019
Paleoclimate reconstruction on the Common Era (1-2000AD) provide critical context for recent warming trends. This work leverages integrated nested Laplace approximations (INLA) to conduct inference under a Bayesian hierarchical model using data from three sources: a state-of-the-art prox database (PAGES 2k), surface temperature observations (HadCRUT4),

Assessing survival time of outpatients with cervical cancer: at the university of Gondar referral hospital using the Bayesian approach

open access: yesBMC Women's Health, 2023
Background Cervical cancer is the 4th most common cancer in women worldwide. as well as the 4th most common cause of cancer-related death. The main objective of this study was to identify factors that affect the survival time of outpatients with cervical
