gam.control {gam}R Documentation

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.
...

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
