Abstract: | Under the assumption of unchanged liability after the occurrence of an accident, the distributions of accident liability in groups can be broken up into probable component distributions of liability for subgroups with different accident records. It is shown that the component distributions have the same form as the total distribution if the latter is of Type III. Accident records have some validity as indicators of accident liability, but relative certainty that particular persons have high accident liability can be achieved only for that small number of cases whose accident records include a large number of accidents. Quantitative examples are given. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
