Family objects for models — family • pareg

Family objects provide a convenient way to specify the details of the models used by pareg. See also stats::family for more details.

family(object, ...)

gaussian(link = c("identity"))

bernoulli(link = c("logit", "probit", "log"))

beta(link = c("logit", "probit", "log"))

beta_phi_lm(link = c("logit", "probit", "log"))

beta_phi_var(link = c("logit", "probit", "log"))

Arguments

object: a object for which the family shoulr be retured (e.g. edgenet)
...: further arguments passed to methods
link: name of a link function

Value

An object of class pareg.family

family: name of the family
link: name of the link function
linkinv: inverse link function
loss: loss function
