Chapter 15 Current frontiers

In this chapter the reader will have encountered a selection of new frontiers in spatio– temporal epidemiology including the following:

• A number of areas that are currently under active development.

• Two modern approaches to addressing the problem of non-stationarity in random spatio– temporal fields; warping and dimension expansion.

• How dimension expansion can be used to dramatically reduce non-stationarity and suggest its possible causes.

• A powerful approach combining both physical and statistical modelling within a single framework.
