fit_vgam( data, age.min = 0.25, age.max = 18, age.int = 1/12, keep.models = F, dist = "BCN", mu.df = 4, sigma.df = 3, nu.df = 2, value )
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() |
mu.df |
degree of freedem location parameter |
sigma.df |
degree of freedem spread parameter |
nu.df |
degree of freedem skewness parameter |
value |
names of the value variable (character) if different from value, ignored |
wrapper around the vgam
function in the VGAM package
returns the fitted lms-parameter at given age points
the function is called inside do_iterations
and may not called directly
list containing a dataframe of the fitted lms parameter at the given age points and the fitted model
