splines2_basis: Create B-Spline basis

In profoc: Probabilistic Forecast Combination Using CRPS Learning

Create B-Spline basis

Description

This function creates a B-Spline matrix.

Usage

splines2_basis(x, knots, deg, periodic = FALSE, intercept = TRUE)

Arguments

x	Vector of values.
knots	Vector of knots.
deg	Degree of the Spline functions.
periodic	Whether the basis should be periodic or not.
intercept	Whether the firs column should be kept.

Value

Returns a matrix of B-Spline basis functions.

Examples

n <- 9
deg <- 3
mu <- 0.35
x <- 0:1000 / 1000

knots <- make_knots(n, mu = mu, deg = deg)

B <- splines2_basis(x, knots, deg)
ts.plot(B, col = 1:dim(B)[2])

# Periodic Case
B <- splines2_basis(x, knots, deg, periodic = TRUE)
ts.plot(B, col = 1:dim(B)[2])
