Offset for Poisson GLM
...is incorporated into the model. But since the number of
observations in a given year, or hour of the day is the desired offset,
rather than a column in my data frame, I'm not sure how to specify that as
an offset in the model:
glm(counts ~ as.factor(year) + as.factor(month) + as.factor(TOD) +
sightability, data=count.data, family=poisson, offset=log(???))
Any ideas will be much appreciated!
Thanks,
