geographically weighted negative binomial regression model?

Hi,

I wonder if anyone know whether there is a R package for implementing a 
geographically weighted negative binomial regression model.
Or is it possible to do this model by using a mgcv package with a family 
= negative.binomial?
I am not sure how to determine the adaptive bandwidth in a gam 
package...... Does anyone out there kindly help?


Thanks in advance.

Not as far as I'm aware. There is draft ggwr() not yet released, which 
could possibly be extended, but you would be on untested ground - as is 
ggwr() anyway.

            

      
      
      
    

        
You could try fixing the other variables and letting gam() choose the 
"bandwidths" for s(x,y) by CV, if you like, but the "bandwidths" are not 
directly comparable with ggwr() bandwidths.
