fitted.freekt: Compute Fitted Values For Free-Knot Spline

Description

This function computes the fitted values, given the amount of the penalty (if applicable) and the locations of the knots.

Usage

# S3 method for freekt
fitted(object, xfit = object@x, …)

Arguments

object

An object of class "freekt" obtained by using one of the fitting algorithms.

xfit

A vector of x values at which to compute the fitted values. Defaults to the x values of the data.

…

Additional arguments to be passed to fitted.freekt. Currently ignored.

Value

A vector containing the fitted values.

residuals.freekt for the residuals.

Examples

# 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)
fitted.freekt(xy.freekt)
