P. Schlattmann et al., COVARIATE ADJUSTED MIXTURE-MODELS AND DISEASE MAPPING WITH THE PROGRAM DISMAPWIN, Statistics in medicine, 15(7-9), 1996, pp. 919-929
The analysis and recognition of disease clustering in space and its re
presentation on a map is an important problem in epidemiology. An appr
oach using mixture models to identify spatial heterogeneity in disease
risk and map construction within an empirical Bayes framework is desc
ribed. Once heterogeneity is detected, the question arises as how expl
anatory variables could be included in the model. A mixed Poisson regr
ession approach to include covariates is presented. The methods are il
lustrated using data for tuberculosis from Berlin in 1991.
