The generation of simulated data in the form of industrial cohorts

A computer program INDCOGEN, which generates data in the form of industrial cohorts, is being made available to interested users. Values for variables which include selection effects, dose-response effects, length of study, staff turnover, plant exposure levels, and underlying rates of mortality are defined by the user. The program can be used to estimate the likelihood of detecting a cancer "hazard" given the parameters of a field study cohort, the likely size of selection effects, and an assumed form of dose-response.
