Alias: none
Argument(s): none
Child Keywords:
| Required/Optional | Description of Group | Dakota Keyword | Dakota Keyword Description | |
|---|---|---|---|---|
| Required (Choose One) | Multilevel Sample Allocation Control (Group 1) | estimator_variance | Variance of mean estimator within multilevel polynomial chaos | |
| rip_sampling | Sample allocation based on restricted isometry property (RIP) within multilevel polynomial chaos |
Multilevel expansions, including regression-based polynomial chaos expansion (PCE) and function train (FT) expansions, require a sample allocation strategy. Three options are currently available:
Default Behavior
Current defaults, when allocation_control is not specified, are estimator variance for PCE and rank sampling for FT.
