This page documents the data definitions used in the Overstay2 scoring models, as defined during re-analysis and generation of Overstay2 model and implemented in Overstay2 module. See Overstay2 Overview for additional context.

See Template:S:\MED\CCMED contains the code that defines these for the model.
