Risks calculationΒΆ

Probabilistic risk is calculated as a distribution of either margin of exposure (MOE) or hazard index (HI), if at least one of the inputs exposure and hazard characterisation is a distribution. The risk distribution is characterised by percentiles. To accommodate for matching results of MOE and HI=1/MOE in the case of percentiles, there is an option to calculate percentiles via the complementary percentile of the inverse distribution in order to handle numerical differences when calculating percentiles for a left or right tail. E.g. p1 of the MOE distribution can optionally be calculated as 1 divided by p99 of the corresponding 1/MOE distribution. For more details about the graphical displays and the calculations see Individual risks.
