A dimension reduction approach to edge weight estimation for use in spatial models
Michael F. Christensen, Jo Eidsvik
Models for areal data are traditionally defined using the neighborhood structure of the regions on which data are observed. The unweighted adjacency matrix of a graph is commonly u…

Incorporating circuit theory into a dynamic model for crowd-sourced observations of migratory birds
Michael F. Christensen, Peter D. Hoff
While the overarching pattern of biannual avian migration is well understood, there are significant questions pertaining to this phenomenon that invite further study. Necessary to…

A flexible and interpretable spatial covariance model for data on graphs
Michael F. Christensen, Peter D. Hoff
Spatial models for areal data are often constructed such that all pairs of adjacent regions are assumed to have near-identical spatial autocorrelation. In practice, data can exhibi…
