I noticed a couple of papers recently where analysts specified a variable as
an offset to control for unequal exposure, AND they included the same
variable as a regressor in the same count model. The Stata manual provides an example of using an exposure variable as an offset and another example of including the variable on the right-hand side of the equation to control for
unequal exposure, but there is no example of including an exposure variable
both as an offset AND as a regressor on the right-hand side simultaneously.
Any thoughts/comments on the appropriateness of this?
Thanks...
