Geographically weighted regression is a powerful and computationally intensive method to model varying spatial relationships, but it may introduce high local multicollinearity which, if not dealt with properly, leads to misleading inference and unreliable results. We introduced a novel solution to deal with multicollinearity by adopting a more localized and refined approach. This solution is demonstrated by modeling the varying local association of childhood obesity and its risk factors at neighborhood level to target only vulnerable neighborhoods for the prevention and control of obesity locally

Abstract

Geographically weighted regression is a powerful and computationally intensive method to model varying spatial relationships, but it may introduce high local multicollinearity which, if not dealt with properly, leads to misleading inference and unreliable results. We introduced a novel solution to deal with multicollinearity by adopting a more localized and refined approach. This solution is demonstrated by modeling the varying local association of childhood obesity and its risk factors at neighborhood level to target only vulnerable neighborhoods for the prevention and control of obesity locally
