This package implements the Bayesian approximation techniques discussed in Kennedy and O'Hagan 2000.
In its simplest form, it takes input from a “slow” but accurate code and a “fast” but inaccurate code, each run at different points in parameter space. The approximator package then uses both sets of model runs to infer what the slow code would produce at a given, untried point in parameter space.
The package includes functionality to work with a hierarchy of codes with increasing accuracy.
