%description
It is a hybrid spatial model that combines the variable selection
capabilities of stepwise regression methods with the predictive power of
the Geographically Weighted Regression(GWR) model.The developed hybrid
model follows a two-step approach where the stepwise variable selection
method is applied first to identify the subset of predictors that have the
most significant impact on the response variable, and then a GWR model is
fitted using those selected variables for spatial prediction at test or
unknown locations. For method details,see Leung, Y., Mei, C. L. and Zhang,
W. X. (2000).<DOI:10.1068/a3162>.This hybrid spatial model aims to improve
the accuracy and interpretability of GWR predictions by selecting a subset
of relevant variables through a stepwise selection process.This approach
is particularly useful for modeling spatially varying relationships and
improving the accuracy of spatial predictions.
