AOR/BOR File

This diskette file contains data used to develop the DRG relative weights. It contains mean, maximum, minimum, standard deviation, and co-efficient of variation statistics by DRG for length of stay and standardized charges. The BOR tables are 'Before Outliers Removed' and the AOR are 'After Outliers Removed.' (Statistical outliers, not payment outliers.)
