The analyses defined for the reporting event. Each analysis is described, using the Analysis class, as a set of operations (i.e., a referenced “AnalysisMethod”) performed on a specified analysis variable for any specified subset of data records (i.e., any referenced “DataSubset”) for a given subject population (i.e., a referenced “AnalysisSet”) which may be subdivided by one or more factors (i.e., any referenced “SubjectGroupingFactor” or “DataGroupingFactor”). The results of each analysis are contained within the “Analysis” class as a property of the analysis and each result is associated with references to all analysis components needed to give the result context (i.e., the operation used to calculate the result and a specific value for each grouping factors used for the analysis such as treatment, sex, age group, etc.).
