MISALIGNED SPATIAL DATA

ABSTRACT: In attempting to establish relationships between spatial variables, one often encounters misaligned data layers. For example, the response variable may be observed on one areal grid and the explanatory variable on another. In some cases one variable is observed areally while the other is observed at point sources. In attempting to reconcile such misalignment, one finds a variety of ad hoc methods in the literature. We propose fully model-based approaches to develop such regressions. Such models are necessarily hierarchical and provide full inference, avoiding typically inappropriate asymptotics associated with likelihood-based approaches. We dicuss general approaches for handling the different types of misalignment and provide illustrative analyses.
