Estimating intervention effects on infectious disease control: The effect of community mobility reduction on Coronavirus spread

SPATIAL STATISTICS, 52.

By: A. Giffin n, W. Gong n, S. Majumder*, A. Rappold*, B. Reich n & S. Yang n

author keywords: Causal inference; COVID-19; Spatiotemporal modeling; SIR model
TL;DR: A spatiotemporal model is proposed that estimates the causal effect of changes in community mobility (intervention) on infection rates and suggests that the reductions in mobility decrease Coronavirus cases 4 to 7 weeks after the intervention. (via Semantic Scholar)

Multivariate spatial prediction of air pollutant concentrations with INLA

ENVIRONMENTAL RESEARCH COMMUNICATIONS, 3(10).

By: W. Gong n, B. Reich n & H. Chang*

author keywords: air pollution; CMAQ; geostatistical model; INLA; linear model of coregionalization
TL;DR: A spatial multipollutant data fusion model that combines monitoring measurements and chemical transport model simulations that leverages dependence between pollutants to improve spatial prediction and provides model-based prediction error estimates is described. (via Semantic Scholar)

Vecchia Approximations of Gaussian-Process Predictions

Katzfuss, M., Guinness, J., Gong, W., & Zilber, D. (2020, June 23). JOURNAL OF AGRICULTURAL BIOLOGICAL AND ENVIRONMENTAL STATISTICS.

author keywords: Computational complexity; Kriging; Large datasets; Sparsity; Spatial statistics
TL;DR: A general Vecchia framework for GP predictions is considered, which contains some novel and some existing special cases, and it is shown that certain choices within the framework can have a strong effect on uncertainty quantification and computational cost, which leads to specific recommendations on which methods are most suitable for various settings.
