Hi,

I have a question about the offset function in glm.nb. As I understod it is possible to use rates in the respons variable in glm.nb with the function offset.

My model, modelA1F<-glm.nb(Tot.dameggs~STATN+offset(log(FECUND)))

Tot.dameggs= total amount of damaged embryos per individual
STATN= Station
FECUND= total number of embryos per individual (huge varability)

My question is if it is possible in this case when FECUND isnt the same for all individuals.

Thanks
/Matias
