From: Evaluation of stability of directly standardized rates for sparse data using simulation methods
Coverage of 95% confidence intervals according to the observed number of categories with no events [Numerical labels denote relative occurrence] and the total expected number of events for the Dobson method when the incidence in the oldest age is 500 times the incidence in the youngest age and the number of people is the same for each age in the sample population. [Grey band indicates “Accurate Coverage”] Rare scenarios, i.e., occurring < 1% of the time, have not been plotted
