Description
When adapting a UQ surrogate model, e.g., by change in
response covariance matrix or level mappings, this option controls the
use of scaling. The absolute
option indicates that there is no
scaling such that the statistical change is compared directly to the
convergence tolerance. The relative
option indicates that the
change is measured relative to the current reference value (which
evolves during the refinement), such that the convergence tolerance
controls the relative change.
Default Behavior
The default is relative
