R: Kriging Smooth Constructor

smooth.construct.kr.smooth.spec {bamlss} | R Documentation

## Kriging Smooth Constructor

### Description

This smooth constructor implements a kriging based model term.

### Usage

    ## S3 method for class 'kr.smooth.spec'
    smooth.construct(object, data, knots, ...)
    ## S3 method for class 'kriging.smooth'
    Predict.matrix(object, data)

### Arguments

`object, data, knots` | See `smooth.construct`.
`...` | Currently not used.

### Details

This smooth constructor implements univariate and bivariate Kriging terms. The basis functions are based on the `matern` function. For finding knots, a space filling algorithm is used, see `cover.design`.

### Value

A smooth specification object, see also `smooth.construct.`

### Examples

    ## Not run: ## Simulate data.
    set.seed(123)
    d <- GAMart()

    ## Estimate model.
    f <- num ~ s(x1,bs="kr") + s(x2,bs="kr") + s(x3,bs="kr") + s(lon,lat,bs="kr",k=30)

    ## Set the seed, estimate model.
    set.seed(111)
    b <- bamlss(f, data = d)

    ## Plot estimated effects.
    plot(b)

    ## End(Not run)
