On the Analysis of Mortality Events Associated with a Prespecified Fixed Point

"A model-based approach to the analysis of disease incidence around a fixed point is presented by considering the radial and directional effects to be expected from emissions from a putative source. In addition we present some score statistics which can be used to test for spatial effects." The methods discussed are applied to the analysis of bronchitis mortality around a reprocessing plant in Bonnybridge, Scotland.
