smooth.construct.ms.smooth.spec

Smooth constructor for monotonic P-splines

Description

The function sets up a smooth term for shape constraint estimation of P-spline model terms. Note that this currently only works using boosting.

Usage

## S3 method for class 'ms.smooth.spec'
smooth.construct(object, data, knots, ...)

Arguments

`object`	Either a smooth specification object, or object of class `"bamlss"`, `"bamlss.frame"`, `"bamlss.formula"` or `"bamlss.terms"`. For smooth specification objects, see function `smooth.construct`.
`data`	A data frame or list, see also see function `smooth.construct`.
`knots`	See function `smooth.construct`.
`...`	Arguments passed to the smooth term constructor functions.

Value

See function see smooth.construct.

Examples

## Not run: ## Generate some data.
d <- GAMart()

## Increasing: constr = 1.
## Decreasing: constr = 2.
b <- bamlss(num ~ s2(x1,bs="ms",xt=list(constr=2)),
  data = d, sampler = FALSE, optimizer = opt_boost)

plot(b)

## End(Not run)
