The complexity of finding and enumerating optimal subgraphs to represent spatial correlation

  title={The complexity of finding and enumerating optimal subgraphs to represent spatial correlation},
  author={Jessica A. Enright and Du-hyun Lee and Kitty Meeks and William Pettersson and John Sylvester},
Understanding spatial correlation is vital in many fields including epidemiology and social science. Lee, Meeks and Pettersson (Stat. Comput. 2021) recently demonstrated that improved inference for areal unit count data can be achieved by carrying out modifications to a graph representing spatial correlations; specifically, they delete edges of the planar graph derived from border-sharing between geographic regions in order to maximise a specific objective function. In this paper we address the…

Improved inference for areal unit count data using graph-based optimisation

A novel graph-based optimisation algorithm for estimating either a static or a temporally varying neighbourhood matrix for the data that better represents its spatial correlation structure, by viewing the areal units as the vertices of a graph and the neighbour relations as the set of edges.

Throughout the 1960s I worked on combinatorial optimization problems including logic circuit design with Paul Roth and assembly line balancing and the traveling salesman problem with Mike Held, which made me aware of the importance of distinction between polynomial-time and superpolynomial-time solvability.

Hard Tiling Problems with Simple Tiles

This work shows that Monotone 1-in-3 Satisfiability is NP-complete for planar cubic graphs, and shows NP-completeness for the domino and straight tromino for general areas on the cubic lattice, and for simply connected regions on the four-dimensional hypercubic lattice.

An explicit link between Gaussian fields and Gaussian Markov random fields: the stochastic partial differential equation approach

It is shown that, using an approximate stochastic weak solution to (linear) stochastically partial differential equations, some Gaussian fields in the Matérn class can provide an explicit link, for any triangulation of , between GFs and GMRFs, formulated as a basis function representation.

Bayesian Spatial Change of Support for Count-Valued Survey Data With Application to the American Community Survey

ABSTRACT We introduce Bayesian spatial change of support (COS) methodology for count-valued survey data with known survey variances. Our proposed methodology is motivated by the American Community

Splitters and near-optimal derandomization

A fairly general method for finding deterministic constructions obeying k-restrictions, which yields structures of size not much larger than the probabilistic bound and imply the very efficient derandomization of algorithms in learning, of fixed-subgraph finding algorithms, and of near optimal /spl Sigma/II/Spl Sigma/ threshold formulae.

Is There Really a “Wrong Side of the Tracks”in Urban Areas and Does It Matter for Spatial Analysis?

Sharp socioeconomic differences between adjacent neighborhoods run counter to Tobler's first law (TFL) of geography and call into question the blanket application of smoothing techniques designed to

A Hierarchical Framework for Correcting Under-Reporting in Count Data

A comprehensive investigation and application of a Bayesian hierarchical approach to modeling and correcting under-reporting in tuberculosis counts, a general problem arising in observational count data.

The Theory of Partitions

The generating functions which occur in the theory of partitions and functions closely related to them belong to two important classes of functions, namely the theta functions and the modular functions, both of which have received much attention and have been most thoroughly investigated since the time of Jacobi.

A Bayesian localized conditional autoregressive model for estimating the health effects of air pollution

The proposed Bayesian localized conditional autoregressive model is flexible spatially, in the sense that it is not only able to model areas of spatial smoothness, but also it is able to capture step changes in the random effects surface.
