ESTIMATING CHANGES IN ACCIDENT STATISTICS DUE TO REPORTING REQUIREMENT CHANGES

The analysis of accident data is made complicated by changes in requirements for reporting accidents. Such changes can obscure or magnify apparent effects of safety programs and of any evaluation based on the reportable accident statistics. A general methodology for estimating the magnitude of change due to the reporting procedure is discussed. The procedure is based on Box-Jenkins time series analysis. An example from South Dakota property-damage-only accident statistics illustrates the procedure.
