DRG costs are devised from most recent or appropriate HCFA data
using the total payments made by medicare for hosp stays by DRG.
This is a highly discounted rate compared to what is actually charged by the hosp.
Total cost is calculated using a base rate (75%) of the charge per DRG
plus the number of hosp days * daily rate determined from average stay per DRG.
Weight by state is due to difference from national average the state's costs are.
