Additional information

The Common Aggregation Hierearchy is an aggregation methodology that can be applied to both HECOS and JACS subject coding frames in order to allow for time series analysis.

The datasets tables Cyy051_SJ (for the Student record) and Cyy054_SJ (for the Student Alternative record) are the HECoS subject by full person equivalent (FPE) tables, that hold merged subject data from the appropriate Course and CourseSubject records apportioned using the HESA 'combination splitter' methodology.

XCAH02 takes the HECoS subject and derives its value based on the HECoS/CAH mapping

XFPE01 apportions the subjects to a nominal FPE, according to the number of subjects submitted per Course and the weighting allocated to a Course's subjects.
