R: Auxilliary for controlling GAM fitting

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.
`...` | 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
