Fitting injury versus exposure data into a risk function.

A problem in safety research is how injury data from accidents, and damage data from laboratory experiments, should be concisely reduced into a single description formula. Well known is the uncertainty that comes from variability of a statistical nature in biological subjects and in the physical course of events producing injuries and damages. A less known source of uncertainty in the violence and loading data is that they most often are censored. The purpose of this paper is to describe what censoring is and how censored data can be analysed.
