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

# NOT RUN {
x <- 0:30/30
truey <- x*sin(10*x)
set.seed(10556)
y <- truey + rnorm(31, 0, 0.2)
xy.freekt <- freelsgen(x, y, degree = 2, numknot = 2, 555)
coef.freekt(xy.freekt)
