[R-sig-Geo] GGWR (family = Poission): Prediction of unknown location

[Zia Ahmed]

Hello,
I am trying to predict expected count for a geographical location  (file 
name:  data_181 - test data)  from a another data set (data_65 - 
work_data)  using GGWR poission model.  Following R code I used.  But No 
predicted counts were  found  in output SDF  file.  I am new in GGWR.   
Help will be appreciated. I attach my data sets here. Thanks
Zia

library(spgwr)
data(data_65)   # work data set
data(data_181) #  test data set

bw <- ggwr.sel(PopRisk_100TH ~ log10(WAS)*log10(GAS)+ 
offset(log(population_1000)), coords=cbind(data_65$x, data_65$y),
       data=data_65, family=poisson())
coordinates(data.181)<-~x+y
ggwr.181 <- ggwr(PopRisk_100TH ~ log10(WAS)*log10(GAS) + 
offset(log(population_1000)), coords=cbind(data.65$x, data.65$y),
       data=data.65,family=poisson(),bandwidth=bw,type = 
c("response"),fit.points = data.181)
