This smooth constructor implements simple linear effects. The columns of the design matrix
are automatically scaled. The main advantage of this constructor is speed when used in
the BAMLSS boosting algorithm boost. Optionally, a ridge penalty can be
added, please see the example.
Usage
## Linear smooth constructor.
lin(...)
## For mgcv.
# S3 method for linear.smooth.spec
smooth.construct(object, data, knots, ...)
Value
Function lin(), similar to function s a simple smooth specification
object.
Arguments
...
For function lin() a formula of the type ~x1+x2+x3 that specifies
the covariates that should be modeled.
