Statistical experimental design has the aim of identifying and quantifying
the relationship between a dependent variable and one or more independent
variables. Constraints on resources and time often prohibit collecting
data for all possible variable settings, so selecting a subset from the
possibilities becomes a necessity. By defining a metric on the design
space, one can use distance to define a "space-filling" criterion which can
be used to select an appropriate subset for an experiment. Space-filling
designs are particularly desirable in computer experimentation where the
models are often quite complex.
Coding theory and design theory share many concepts. The space-filling
design problem will be linked to coding theory, and the results of this
link will be presented. The results include the identification of several
families of space-filling designs as well as a catalog of space-filling
designs for up to 27 independent factors (where previous work covered only
up to 7 independent factors).
