DESCRIPTION:When we build an emulator to analyse a computer experiment the
  normal practice is to use a two stage approach to design. An initial spac
 e filling design is used to build the emulator. A second experiment is the
 n carried out to validate the emulator. In this paper I will consider what
  form this validation experiment should take. Current practice is to use a
 nother space filling design\, unrelated to the first. Clearly we want our 
 validation design to be space filling\, we want to validate the emulator e
 verywhere. But we might have other criteria as well for validation. For in
 stance we might want to make sure that we validate our estimate of the spa
 tial scales in which case we want our validation design to include points 
 at varying distances from our original design.\n
