[R-sig-Geo] spatial count regression model

[Alok K Bohara, PhD]

Dear all:

Do you know of any R package that can to do spatial regression poisson 
or spatial regression NB model (not using the filtering) by taking into 
account the spatial correlation --neighborhood effect.  I am looking for 
something that can do e.g., CAR type models.  I used spatcounts to do a 
spatial poisson but the spatial correlation (gamma and psi) both turned 
out to be 0, showing that there is no spatial effect (I think).  Yet, I 
know there is a strong spatial effect in  my data.   I just have a one 
set of count data on 800 cells with co-variates (30 % with 0) --that is, 
no repeated counts for each cells.   Thanks.

Best,
Alok Bohara
