seqDesign.class: A Reference Class to generate a better Model2 or Model4...
In CaliCo: Code Calibration in a Bayesian Framework

Description Usage Format Fields References

This class generates a new model.class for Model4 and Model2. Based on the previous estimation of the Gaussian process in the function model, the design of experiments previously used is improved according to [Damblin et al. 2018]. The aim is to reduce the error produced by the initial estimation of the Gaussian process by fortifying the initial DOE. The method consists in proposing new points based on the expectancy improvement criterion.

Fields should not be changed or manipulated by the user as they are updated internally during the estimation process.
