PROBLEMS OF INFERENCE IN STUDIES OF SEAT BELT EFFECTIVENESS

The report contains a theoretical discussion of problems of inference in studies of seat belt effectiveness. Seat belt effectiveness in accidents is initially discussed from a population parameter point of view. Three measures are introduced and their features explored. Several inferential problems are discussed, certain simplifications obtained, and some methodology is developed. A new tool is developed for investigating the bivariate injury distribution for belted and unbelted drivers to provide insight into the mechanism of the injury-reducing potential of belts in accidents.
