RepresentedVariable¶
Generalization is ConceptualVariable.
Superclass hierarchy
Definition¶
ConceptualVariable with a substantive value domain specified.
Examples¶
The pair (Number of Employees, Integer), where “Number of Employees” is the characteristic of the population (Variable) and “Integer” is how that measure will be represented (Value Domain).
Explanatory notes¶
Extends from ConceptualVariable and can contain all descriptive fields without creating a ConceptualVariable. By referencing a ConceptualVariable it can indicate a common relationship with RepresentedVariables expressing the same characteristic of a universe measured in another way, such as Age of Persons in hours rather than years. RepresentedVariable constrains the coverage of the UnitType to a specific Universe. In the above case the Universe with the measurement of Age in hours may be constrained to Persons under 5 days (120 hours old). RepresentedVariable can define sentinel values for multiple storage systems which have the same conceptual domain but specialized value domains.
