Dear list, i am using spgwr as an exploratory tool in the analysis of environment-health associations. The study area is square, with dimensions 100x100 m. In one of the results of my analysis, i found an optimal bandwidth (optimizing the CV score) of 507 m. And I interpret this bandwidth as a buffer distance where CV is the smallest. However, maximum (Euclidean) distance between any 2 points in the grid (100x100) is 141,42 m, so I would expect an optimal bandwidth varying between zero and 141 m. I am missing something in the interpretation of this result, since the optimal bandwidth is 507 m. If anyone can help me interpreting this correctly I will be deeply appreciated Kind regards Manuel Manuel C Ribeiro Cerena - Centro de Recursos Naturais e Ambiente Instituto Superior T?cnico Av.
