Implementing approximate Bayesian inference for survival analysis using integrated nested Laplace approximations

open access: yes, 2010
This manual describes theinla program, a new instrument which allows the user to easily perform approximate Bayesian inference using integrated nested Laplace approximation (INLA). We describe the set of models which can be solved by the inla program and

The impact of climatic factors on negative sentiments: An analysis of human expressions from X platform in Germany

open access: yesiScience
Summary: Expressions in social media can provide a rapid insight into people’s reactions to events, such as periods of climatic stress. This study explored the link between climatic stressors and negative sentiment on the X platform in Germany to inform ...

Spatial distribution of dengue incidence and socio-environmental conditions in Campinas, São Paulo State, Brazil, 2007

open access: yesCadernos de Saúde Pública, 2013
This study aimed to analyze the spatial distribution of dengue risk and its association with socio-environmental conditions. This was an ecological study of the counts of autochthonous dengue cases in the municipality of Campinas, São Paulo State, Brazil,

Estimating Empirical Ground-Motion Models including Spatial correlations with the Integrated Nested Laplace Approximation

open access: yes
A Bayesian method to include spatial correlation structure of residuals in empirical ground-motion models is presented, based on the integrated nested Laplace approximation. The method is evaluated on a simulated data set as well as Italian strong-motion

Designing Proposal Distributions for Particle Filters using Integrated Nested Laplace Approximation

open access: yes, 2023
State-space models are used to describe and analyse dynamical systems. They are ubiquitously used in many scientific fields such as signal processing, finance and ecology to name a few. Particle filters are popular inferential methods used for state-space methods. Integrated Nested Laplace Approximation (INLA), an approximate Bayesian inference method,

Spatiotemporal analysis of leptospirosis in Colombia from 2007 to 2021. An environmental health metrics approach

open access: yesCritical Public Health
Leptospirosis is a global zoonosis and environmental health problem because of its strong association with environmental factors. Although spatiotemporal statistics can estimate area-specific risk indicators, very few spatiotemporal analyses are done at ...

Model selection for mixture model via integrated nested Laplace approximation

open access: yesElectronics Letters, 2015
To cluster or partition data/signal, expectation‐and‐maximisation or variational approximation with a mixture model (MM), which is a parametric probability density function represented as a weighted sum of K̂ densities, is often used. However, model selection to find the underlying K̂ is one of the key concerns in MM clustering, since the desired ...
