A function, describing the link-function from a model-object. For multivariate-response models, a list of functions is returned.
# example from ?stats::glm counts <- c(18, 17, 15, 20, 10, 20, 25, 13, 12) outcome <- gl(3, 1, 9) treatment <- gl(3, 3) m <- glm(counts ~ outcome + treatment, family = poisson()) link_function(m)(.3) # same as log(.3)
