Improved inference for areal unit count data using graph-based optimisation
Duncan Lee, Kitty Meeks
Spatial correlation in areal unit count data is typically modelled by a set of random effects that are assigned a conditional autoregressive (CAR) prior distribution. The spatial c…
The complexity of finding and enumerating optimal subgraphs to represent spatial correlation
Jessica Enright, Duncan Lee, Kitty Meeks +2
Understanding spatial correlation is vital in many fields including epidemiology and social science. Lee, Meeks and Pettersson (Stat. Comput. 2021) recently demonstrated that impro…
Directed branch-width: A directed analogue of tree-width
Benjamin Merlin Bumpus, Kitty Meeks, William Pettersson
Gurski and Wanke showed that a graph class C has bounded tree-width if and only if its associated class of directed line graphs has bounded clique-width. Inevitably -- asking wheth…
