approximator (version 1.2-7)

Bayesian Prediction of Complex Computer Codes

Description

Performs Bayesian prediction of complex computer codes when fast approximations are available. It uses a hierarchical version of the Gaussian process, originally proposed by Kennedy and O'Hagan (2000), Biometrika 87(1):1.
