Title: Change of Support in Dynamical Spatio-Temporal Models
Author(s): Christopher Wikle*+
Companies: University of Missouri
Address: 146 Middlebush Hall, Columbia, MO, 65211,
Keywords: support ; dynamical ; spatio-temporal ; hierarchical

There are many situations in socio-economic demographic data analysis in which the data come aggregated at various levels of support across space and time. It is often advantageous to consider a common level of support for the associated "true" dynamical process in order to facilitate inference and prediction (subject to the usual caveats related to the modifiable areal unit problem). We make use of a hierarchical modeling structure to accommodate such change of support for dynamical spatio-temporal models, allowing for efficient borrowing of information across space and time.
