Details
The data arise from 1125 original groups insured during all or part of
the period 1982-85 by a major Nowegian insurance company. Exposures
can be normalize by a factor of 344 as in Hastrup (2000) and then can be
interpreted as the apriori expected number of claims (deaths) for each group.
The original 1125 groups were aggregated into 72 as in Norberg (1989).
