Kryging: Geostatistical analysis of large-scale datasets using Krylov subspace methods

1 code implementation24 Dec 2020 Suman Majumder, Yawen Guan, Brian J. Reich, Arvind K. Saibaba

Analyzing massive spatial datasets using Gaussian process model poses computational challenges.

Methodology Computation

A spectral adjustment for spatial confounding

no code implementations22 Dec 2020 Yawen Guan, Garritt L. Page, Brian J Reich, Massimo Ventrucci, Shu Yang

We show that this assumption in the spectral domain is equivalent to adjusting for global-scale confounding in the spatial domain by adding a spatially smoothed version of the treatment variable to the mean of the response variable.

Methodology

Probabilistic Projections of Baseline 21st Century CO$_2$ Emissions Using a Simple Calibrated Integrated Assessment Model

1 code implementation6 Aug 2019 Vivek Srikrishnan, Yawen Guan, Richard S. J. Tol, Klaus Keller

Our global sensitivity analysis identifies several key economic drivers of uncertainty in future emissions and shows important higher-level interactions between economic and technological parameters, while population uncertainties are less important.

Applications

Nearest-Neighbor Neural Networks for Geostatistics

no code implementations28 Mar 2019 Haoyu Wang, Yawen Guan, Brian J. Reich

We propose a more flexible spatial prediction method based on the Nearest-Neighbor Neural Network (4N) process that embeds deep learning into a geostatistical model.
