Auxilliary for controlling GAM fitting

Auxiliary function as user interface for 'gam' fitting. Typically only used when calling 'gam' or 'gam.fit'.

gam.control(
  epsilon = 1e-07,
  bf.epsilon = 1e-07,
  maxit = 30,
  bf.maxit = 30,
  trace = FALSE,
  ...
)

Arguments

epsilon

convergence threshold for local scoring iterations

bf.epsilon

convergence threshold for backfitting iterations

maxit

maximum number of local scoring iterations

bf.maxit

maximum number of backfitting iterations

trace

should iteration details be printed while gam is fitting the model.

...

placemark for additional arguments

Value

a list is returned, consisting of the five parameters, conveniently packaged up to supply the control argument to gam. The values for gam.control can be supplied directly in a call to gam; these are then filtered through gam.control inside gam.

Examples

if (FALSE) gam(formula, family, control = gam.control(bf.maxit=15)) # \dontrun{}
if (FALSE) gam(formula, family, bf.maxit = 15) # these are equivalent # \dontrun{}
