Multivariate Spatio-Temporal Regression with Penalized Model Selection and an Empirical Application

This paper develops the statistical foundations of a multivariate general nesting spatio-temporal (MGNST) regression framework for analyzing spatial, temporal, and cross-equation dependence among responses. Four parameter matrices represent spatial lag dependence, spatial error dependence,temporal autoregression, and c...

Multivariate Spatio-Temporal Modeling for Regional GIS Data: A Statistical Framework for Analyzing Multidimensional Spatial Interactions

An open-source, reproducible workflow for comparing multivariate spatio-temporal regression models that allow for cross-equation dependence against separate single-equation spatial regressions using interactive map-based diagnostics is presented.
