Spatial structure effects in spatial interaction model: a Geographically Weighted Regression (GWR) approach
Abstract
En
The development of local forms of spatial analysis has been the subject of intense research over last decade. In this paper we propose a local calibration procedure for handling varying parameter estimates of an origin-constrained spatial interaction model. In this context, the estimates of local parameters depends both on origins and destinations and a four dimensional space is involved. A suitable estimation of local parameters can be obtained by the maximisation of a weighted maximum likelihood function, exploiting the same principle of geographical weighted regression (GWR) approach.
