gam.control: Auxilliary for controlling GAM fitting

In gam: Generalized Additive Models

Auxilliary for controlling GAM fitting

Description

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

## Not run: gam(formula, family, control = gam.control(bf.maxit=15))
## Not run: gam(formula, family, bf.maxit = 15) # these are equivalent
