precompute: Precompute objects

In hero: Spatio-Temporal (Hero) Sandwich Smoother

Precompute objects

Description

This function is an internal function to compute objects needed for fast implementation of the sandwich smoother. It is meant to be an internal function, so use this at your own risk.

Usage

precompute(B, P, m)

Arguments

B	A matrix of basis functions
P	A penalty matrix
m	Difference order of P-spline

Value

A list of needed objects

Examples

object = bspline(nbasis = 10)
# sequence to evaluate
evalarg = seq(0, 1, len = 11)
# penalty matrix
D = diffpen(object)
P = Matrix::crossprod(D)
B = predict(object, evalarg)
stuff = precompute(B, P, m = 2)
