Ecological Inference Incorporating Spatial Dependence
Ecological inference for a series of 2 × 2 tables suffers from an inherent lack of identifiability. Any attempt at a solution to this inferential problem must either (a) incorporate additional information or (b) make assumptions. Without further information and given the data in the margins alone, critical assumptions, such as that of no contextual effects, remain untestable . This suggests a s...
متن کاملA Mereological Approach to Representing Spatial Vagueness*
Spatial reasoning is crucial in many AI application domains, such as robotics, qualitative and naive physics, and some types of planning . Qualitative reasoning is often required ; and in many of these cases, uncertainty or imprecision about the spatial extent of particular entities has to be represented and coped with . This paper develops an axiomatisation of a relation of `crisping' (reducin...

متن کاملMeasuring Spatial Dependence for Infectious Disease Epidemiology
Global spatial clustering is the tendency of points, here cases of infectious disease, to occur closer together than expected by chance. The extent of global clustering can provide a window into the spatial scale of disease transmission, thereby providing insights into the mechanism of spread, and informing optimal surveillance and control. Here the authors present an interpretable measure of s...
متن کاملSpatial Pattern and Characteristic of Tree-fall Gaps to Approach Ecological Forestry in Northern Iran
Gaps created by falling trees (tree-fall gaps) are a natural disturbance in forest ecosystems. Understanding scale, pattern and the effect of gaps on regeneration is important to current and future forest management. The aim of this study was to determine the size, shape and the spatial pattern of tree-fall gaps and of associated regeneration. This study was carried out in three parcels (No.15,...
