Big thanks! The offset variable should be "population" as I
have understood it.
But I don´t really understand how to implement it, do you?
What the offset variable should be depends on how your model is specified
and what aims to describe; in fact, it may be the case that you don't need
an offset variable at all.
If you need a literature pointer to clarify the matter, the concept is
briefly but clearly explained in Greene(2012, 7th ed.) in Section 18.4.5,
at the start of page 808.
