Dear userRs, 

when applied the summary function to a glm fit (e.g Poisson) the parameter
table provides the categorical variables assuming that the first level
estimate (in alphabetical order) is 0. 

What is the standard error for that variable then? 

Are the standard errors calculated assuming a normal distribution?

Many thanks,
