Offset option for Poisson regression

With grpreg, I see that you have the option to use the Poisson distribution for the family, but I am unable to find an option to include an offset with this. I was wondering if there is a way to do so using the package.

You raise an excellent point. Unfortunately, this option has not yet been implemented in grpreg. I am certainly aware that without such an option, the utility of grpreg for Poisson regression is greatly limited, so this is definitely on my to-do list.

Very interesting package and has most what I was looking for! However, I often use Poisson regression and was also missing the offset option. Are you able to give any timeline with regard to the implementation? Are we talking about weeks or months?

[pbreheny]

More like months than weeks. Not that it would necessarily take a long time, it's just that there's not much reward in it for me, as I have no projects going on that involve Poisson regression.

+1, this would be awfully handy for my work as well.
