Note that the ARS Model is designed to support the specification of analyses of data in ADaM datasets, which are expected to be "analysis-ready." In analysis-ready datasets, any complex criteria needed to define either subject populations or the grouping of data for analysis will usually have been applied to create flagging or grouping variables. These flagging and grouping variables can usually then be referenced in the specification of simple conditions, so compound expressions should generally not be required for the definition of subject populations (using the AnalysisSet class) or groups within grouping factors (using either the AnalysisGroup or DataGroup specialization of the Group class). |
