Notes: Total cost and days for each event report type of is calculated by multiplying the type-specific per event estimate by the number events of that type. The total cost and days reported above is the sum of the type-specific total cost and days to reflect the frequency of each event type. The overall cost and days per event estimate reported above in italics is from the initial regressions that did not contain type dummy variables and is not used in the calculation of total cost and days.
