gamlss (version 5.1-4)

refit: Refit a GAMLSS model

Description

This function refits a GAMLSS model. It is useful when the algorithm has not converged after 20 outer iteration (the default value)

Usage

refit(object, ...)

Arguments

object

a GAMLSS fitted model which has not converged

…

for extra arguments

Value

Returns a GAMLSS fitted model

Details

This function is useful when the iterations have reach the maximum value set by the code(n.cyc) of the gamlss.control function and the model has not converged yet
