Query: Accurate emulators for large-scale computer experiments   Large-scale computer experiments are becoming increasingly important in
science. A multi-step procedure is introduced to statisticians for modeling
such experiments, which builds an accurate interpolator in multiple steps. In
practice, the procedure shows substantial improvements in overall accuracy, but
its theoretical properties are not well established. We introduce the terms
nominal and numeric error and decompose the overall error of an interpolator
into nominal and numeric portions. Bounds on the numeric and nominal error are
developed to show theoretically that substantial gains in overall accuracy can
be attained with the multi-step approach.
