Selection of statistics to compute at each response level
Alias: none
Argument(s): none
Default: probabilities
Child Keywords:
| Required/Optional | Description of Group | Dakota Keyword | Dakota Keyword Description | |
|---|---|---|---|---|
| Required (Choose One) | Statistics to Compute (Group 1) | probabilities | Computes probabilities associated with response levels | |
| gen_reliabilities | Computes generalized reliabilities associated with response levels | |||
| Optional | system | Compute system reliability (series or parallel) | ||
The compute keyword is used to select which forward stastical mapping is calculated at each response level.
Default Behavior
If response_levels is not specified, no statistics are computed. If response_levels is specified but compute is not, probabilities will be computed by default. If both response_levels and compute are specified, then on of the following must be specified: probabilities, reliabilities, or gen_reliabilities.
Expected Output
The type of statistics specified by compute will be reported for each response level.
Usage Tips
CDF/CCDF probabilities are calculated for specified response levels using a simple binning approach.
CDF/CCDF reliabilities are calculated for specified response levels by computing the number of sample standard deviations separating the sample mean from the response level.
