fit_gamlss: fit lms

Description

fit lms

Usage

fit_gamlss(data, age.min = 0.25, age.max = 18, age.int = 1/12,
  dist = "BCCGo", mu.df = 4, sigma.df = 3, nu.df = 2, tau.df = 2,
  value)

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
dist
distribution used for the fitting process, has to be one of BCCGo, BCPEo, BCTo as they are accepted by lms()
mu.df
degree of freedem location parameter
sigma.df
degree of freedem spread parameter
nu.df
degree of freedem skewness parameter
tau.df
degree of freedem kurtosis parameter
value
names of the value variable (character) if different from value, ignored

Value

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

Details

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