Class: OperationResult
The OperationResult class is used in the results attribute of an analysis to represent the results of the analysis.
An instance of the OperationResult is created for each individual "statistic" value generated by the analysis. There will be at least 1 instance for each statistical operation defined for the method specified in the methodId attribute of the analysis. For analyses with at least one grouping factor that is marked as generating a result for each group (the resultsByGroup attribute of the OrderedGroupingFactor class has a value of "true"), there will be 1 instance for statistical operation and for each combination of groups within results-by-group groupings. For example:
- In a simple analysis for "count of subjects in the safety population", where the associated analysis method only has a single operation (i.e., "Count of subjects") and there are no results-by-group groupings, there will only be 1 result value (i.e., only one instance of the OperationResult class).
- In an analysis for "summary of subjects by treatment and sex", where the analysis method has 2 operations (i.e., "Count of subjects" and "Percent of subjects") and there are 2 results-by-group groupings:
- "Treatment" with 3 groups: "Placebo", "Drug A", and "Drug B"
- "Sex" with 2 groups: "Male" and "Female"
There will be a total of 12 individual result values (i.e., 12 instances of the OperationResult class) - one for each combination of operation, treatment group and sex group:
| Operation | Treatment | Sex |
|---|---|---|
| Count of subjects | Placebo | Male |
| Count of subjects | Placebo | Female |
| Count of subjects | Drug A | Male |
| Count of subjects | Drug A | Female |
| Count of subjects | Drug B | Male |
| Count of subjects | Drug B | Female |
| Percent of subjects | Placebo | Male |
| Percent of subjects | Placebo | Female |
| Percent of subjects | Drug A | Male |
| Percent of subjects | Drug A | Female |
| Percent of subjects | Drug B | Male |
| Percent of subjects | Drug B | Female |
