From the developer:
GWR4 is a tool for modelling varying relationships among variables by calibrating Geographically Weighted Regression (GWR) and Geographically Weighted Generalized Linear Models (GWGLM) with their semi-parametric variants. It allows you to fit a range of GWR models including conventional Gaussian models as well as extensions based on the generalised linear modelling (GLM) framework.
