Event size probability distribution for risk analysis

Research output: Contribution to journalConference articlepeer-review


Environmental risk may be defined as the probability of environmental or health loss. Often it is necessary to estimate probability distributions for loss magnitude, for planning and design. Data for such event size probability distributions for industrial gas explosions are compared here to various empirical relations and distributions. A form of the Pareto distribution is derived using information theory and Bayesian statistics, and compared to the data, as well. Where the probability of extremely large events is of interest, the Bayesian distribution provides the closest empirical fit.
