An additive binomial fit can be converted into an additive
Poisson fit via the multinomial–Poisson transformation
(Baker, 1994). This function transforms the data as
described by Donoghoe and Marschner (2014) and passes it to
with a Poisson family to get the maximum likelihood
estimate. The coefficients (and other values) from the
Poisson model are transformed back to relate to the
additive binomial model.
This is a workhorse function for

be called directly.
