WebFor a binomial GLM prior weights are used to give the number of trials when the response is the proportion of successes: they would rarely be used for a Poisson GLM. glm.fit is the workhorse function: it is not normally called directly but can be more efficient where the response vector, design matrix and family have already been calculated. Webglm( numAcc˜roadType+weekDay, family=poisson(link=log), data=roadData) ﬁts a model Y i ∼ Poisson(µ i), where log(µ i) = X iβ. Omitting the linkargument, and setting family=poisson, we get the same answer because the log link is the canonical link for the Poisson family.
