ABSTRACT

In this study, Bayesian methods were applied to stabilize the variance of mortality. We explored and applied several variance stabilizing transformations. As an application study, we produced the maps of prostate cancer mortality in South Korea for the first time. In addition, we made a comparison between the maps of the posterior distribution of mortality and the standardized mortality ratio (SMR). As a result, the relative risks calculated from the Bayesian modeling were found to have more stabilized variance of mortality than SMR. The strength of variability shrinkage of the statistics applying local (spatial) Bayesian modeling that has been developed based on the idea of pooling information from neighboring areas was not larger than other stabilizing transformations.
