질병지도 작성을 위해 공간모형을 이용한 소지역 추정

Abstract

SMRs (standardized mortality rates) for major diseases, accidents, cancer, cerebrovascular diseases, and cardiovascular diseases are considered in small areas of administrative units such as Eup/Myeon/Dong from years 2005 to 2008. Due to small sample issue in small areas, the precision of directly estimated crude SMR for each area can be poor. In this study, we consider the HGLM (hierarchical generalized linear model) with MRF (markov random field) to account for the spatial correlations among the small areas. The effects of covariates for cause of mortality by Dongs in Seoul and disease maps based on the estimated SMR are presented. The results suggest how we analyze and interpret the difference in mortalities by small areas such as Dongs by revealing the spatial patterns.
