I am running a simple example of GLM. If I include weights when
family="poisson" then the weights are calculated iteratively and
$weights and $prior.weights return different values. The $prior.weights
are what I supplied and $weights are the "posterior" weights of the
IWLS. If I include weights with family="gaussian" then the weights are
static and $weights and $prior.weights return the same values; it seems
to ignore IWLS algorithm procedure. I really want the family="poisson"
to behave like the family="gaussian" and use the static weights. Thoughts?
