Statistics mode for refinement metric (Group 1) active

use statistics for the active expansion within multifidelity refinement

combined

use statistics for the combined expansion within multifidelity refinement

Description

When performing adaptive refinement in multifidelity UQ methods, one can adapt the expansion for a model level/fidelity based on its local statistics (active) or based on the statistics for the aggregate expansion (combined). The latter case may incur additional computational overhead, but ensures that the refinement occurs in the aggregate multifidelity context.

Default Behavior

Default for multifidelity methods is combined statistics.
