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, ...)

Value

Returns a GAMLSS fitted model

Arguments

object

a GAMLSS fitted model which has not converged

...

for extra arguments

Author

Mikis Stasinopoulos , Bob Rigby

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
