glim.control {gamlss}

Auxiliary for Controlling the inner algorithm in a GAMLSS Fitting

Description

Auxiliary function used for the inner iteration of gamlss algorithm. Typically only used when calling gamlss function through the option i.control.

Usage

glim.control(cc = 0.001, cyc = 50,  glm.trace = FALSE, 
             bf.cyc = 30, bf.tol = 0.001, bf.trace = FALSE, 
             ...)

Arguments

cc

the convergence criterion for the algorithm

cyc

the number of cycles of the algorithm

glm.trace

whether to print at each iteration (TRUE) or not (FALSE)

bf.cyc

the number of cycles of the backfitting algorithm

bf.tol

the convergence criterion (tolerance level) for the backfitting algorithm

bf.trace

whether to print at each iteration (TRUE) or not (FALSE, the default)

...

for extra arguments

Value

A list with the arguments as components
