Statistical Modeling of Spatial Extremes [PDF]

open access: yes, 2012
The areal modeling of the extremes of a natural process such as rainfall or temperature is important in environmental statistics; for example, understanding extreme areal rainfall is crucial in flood protection.

Inferring spatial causations from spatial associations considering spatial lags: a case study of geohazards in Yunnan, China

open access: yesAnnals of GIS
The inference of causation is essential for interpretable scientific research and evidence-based policymaking. Existing causal methods – including those based on intervention, forecasting, and graph models – have achieved considerable success in non ...

Cortical hierarchies perform Bayesian causal inference in multisensory perception.

open access: yesPLoS Biology, 2015
To form a veridical percept of the environment, the brain needs to integrate sensory signals from a common source but segregate those from independent sources.

A max-stable process model for rainfall extremes at different accumulation durations

open access: yesWeather and Climate Extremes, 2016
A common existing approach to modeling rainfall extremes employs a spatial Bayesian hierarchical model, where latent Gaussian processes are specified on distributional parameters in order to pool spatial information.

A multi-resolution approximation for massive spatial datasets

open access: yes, 2015
Automated sensing instruments on satellites and aircraft have enabled the collection of massive amounts of high-resolution observations of spatial fields over large spatial regions.

Inferring multi-scale neural mechanisms with brain network modelling

open access: yeseLife, 2018
The neurophysiological processes underlying non-invasive brain activity measurements are incompletely understood. Here, we developed a connectome-based brain network model that integrates individual structural and functional data with neural population ...

Assessing Survey Design for Long-Term Population Trend Detection in Piping Plovers

open access: yesLand
Determining appropriate spatio-temporal scales for monitoring migratory shorebirds is challenging. Effective surveys must detect population trends without excessive or insufficient sampling, yet many programs lack formal evaluations of survey ...

Two contrasting spatial processes with a common variogram: inference about spatial models from higher‐order statistics

open access: yesEuropean Journal of Soil Science, 2010
Geostatistical analysis of soil properties is undertaken to allow prediction of values of these properties over regions or at unsampled locations. A key step in geostatistical analysis is the estimation of a variogram function that describes the spatial covariance structure of the variable in question. If it can be assumed plausibly that the data are a

State estimation for temporal point processes [PDF]

open access: yes, 2015
This paper is concerned with combined inference for point processes on the real line observed in a broken interval. For such processes, the classic history-based approach cannot be used.

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...
