ReferenceVariable

Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::DataDescription::Long::ReferenceVariable

Definition

Variable that records values of multiple variables in the context of a data structure. Variable playing the role of a variable value component.

Examples

Consider two variables, i.e. income and age, with values appearing in the same column, e.g. 100000, 45, 85000, 34, etc. Values 100000, 45, 85000, 34 are reference values in the reference value domain corresponding to the reference variable.
