I have a Poisson model with the following true relationship:
$$E(y \mid x, z)=exp(bx+cz)$$
Is it possible to apply here some nonlinear version of the Frisch-Waugh-Lovell theorem?
(Note that an earlier post tried to ask the same question, but the question's text contained errors -- like 1) not specifying the conditional mean correctly and 2) maybe being too specific about how the nonlinear version of FWL would look like -- and did not receive any pertinent replies.)
