coef.freekt: Compute Coefficients of B-Splines For Free-Knot Splines

In freeknotsplines: Algorithms for Implementing Free-Knot Splines

Description

This function computes the coefficients of the B-splines for free-knot splines, given the amount of the penalty (if applicable) and the locations of the knots.

Usage

## S3 method for class 'freekt'
coef(object, ...)

Arguments

object	An object of class "freekt" obtained by using one of the fitting algorithms.
...	Additional arguments to be passed to coef.freekt. Currently ignored.

Value

A vector containing the coefficients of the B-splines.

Examples

x <- 0:30/30
truey <- x*sin(10*x)

y <- truey + rnorm(31, 0, 0.2)
xy.freekt <- freelsgen(x, y, degree = 2, numknot = 2, 555)
coef.freekt(xy.freekt)
