Different methods are needed to propagate ignorance and variability
There are two kinds of uncertainty. One kind arises as variability resulting from heterogeneity or stochasticity. The other arises as partial ignorance resulting from systematic measurement error orExpand

Model validation and predictive capability for the thermal challenge problem
We address the thermal problem posed at the Sandia Validation Challenge Workshop. Unlike traditional approaches that confound calibration with validation and prediction, our approach strictlyExpand
