Description
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.
Examples
