[hlehmann17]

Generalization: Normalizing Values	In Measurement, Observation	Where Implemented
For all numerical concept IDs [ OR set of given concept IDs]	List of target concept ids	Concept ID white list
Get frequency distributions of units		Data Quality Portal
...Unmapped, Mapped to 0, some other information
...Are we allowed to impute units? (from population? from other measurements within patient)
Determine significance of the distribution
....Is there problematic data partner?	Look for units = 0
....Do different source data models (even tables within CDMs) behave differently?	e.g., Obs_Clin
Articulate a formula for normalizing values and units
Fill the (new) column, Normalized_value, Normalized_unit
