Abstract:
|
We develop a novel method of confidence interval construction for directly standardized rates. These intervals involve saddlepoint approximations to the intractable distribution of a weighted sum of Poisson random variables and the determination of hypothetical Poisson mean values for each of the age groups. Simulation studies show that, in terms of coverage probability and length, the saddlepoint confidence interval outperforms four competing confidence intervals obtained from the moment matching, gamma-based and ABC bootstrap methods.
