[R-sig-Geo] geographically weighted negative binomial regression model?

[Takatsugu Kobayashi]

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.
