Auxilliary for controlling GAM fitting

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

Usage

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{}
