In rdmatheus/ugrpl: Unit Gamma Regression with Parametric Link Functions for Modeling Rates and Proportions

Choosing the Link Function in the Unit Gamma Regression

Description

Choosing the Link Function in the Unit Gamma Regression

Usage

plink_choice(
  object,
  link,
  sigma.link,
  criterion = c("aic", "bic", "upsilon"),
  control = ug_control(...),
  ...
)

Arguments

object	a "ugrpl" object.
link, sigma.link	a vector of characters specifying which link functions should be considered for the mean and dispersion parameter submodels, respectively. By default, possible combinations between the link functions "logit", "probit", "plogit", "pprobit", "rplogit", "rpprobit", "aordaz", and "raordaz" are considered. See make.plink.
criterion	criteria for choosing the "best" combination. AIC, BIC, or Upsilon statistics can be used.
control	a list of control parameters passed as arguments for the optim function specified via ug_control.
...	arguments passed to ug_control.

Value

The plink.choice function returns a list where each component is a unit gamma regression fit with a combination of the links provided by the link and sigma.link arguments.
