fit_gamlss1

Description

fit_gamlss

Usage

fit_gamlss1(
  data,
  age.min = 0,
  age.max = 80,
  age.int = 1/12,
  keep.models = F,
  dist = "BCCGo",
  formula = NULL,
  sigma.formula = ~1,
  nu.formula = ~1,
  tau.formula = ~1,
  method.pb = "ML"
)

Arguments

data	dataframe as return by select_meas()
age.min	lower bound of age
age.max	upper bound of age
age.int	stepwidth of the age variable
keep.models	indicator whether or not models in each iteration should be kept
dist	distribution used for the fitting process, has to be one of BCCGo, BCPEo, BCTo as they are accepted by lms()
formula	formula for the location parameter
sigma.formula	formula for the sigma parameter
nu.formula	formula for the nu parameter
tau.formula	formula for the tau parameter
method.pb	GAIC or ML

Details

wrapper around the gamlss function from the gamlss package returns the fitted lms-parameter at given age points the function is called inside do_iterations and may not be called directly

Value

list containing a dataframe of the fitted lms parameter at the given age points and the fitted model
