Abstract:
|
We consider dimension reduced approaches to space-time analysis based on modeling the spatial structure in terms of a low number of specified basis functions. The temporal evolution of the space-time process is then modeled through the amplitudes of the basis functions. We will discuss ways to extend these ideas to modeling two space-time processes and show an example of downscaling temperatures over the Antarctic.
