Creating and SplineBasis Objects.
The function to create
1 2 3
The full set of knots used to define the basis functions.
Order of the spline fit.(degree= order-1)
Should duplicate interior knots that could cause computation problem be kept or removed. Defaults to false, which removes duplicate knots with a warning if duplicate interior knots are found.
Other arguments either ignored or passed onto other functions.
SplineBasis produces an object representing the basis functions used in spline fitting. Provides a compact easily evaluated representation of the functions. Produces a class of object
OrthogonalSplineBasis is a shortcut to obtain a set of orthogonalized basis functions from the knots.
OBasis is an alias for
OrthogonalSplineBasis. Both provide an object of class
OrthogonalSplineBasis. The class
OrthogonalSplineBasis inherits directly from
SplineBasis meaning all functions that apply to SplineBasis functions also apply to the orthogonalized version.
Object of class SplineBasis or OrthogonalSplineBasis
