Create a List of Basis Matrices — make_basis

This function creates a list of basis matrices and the corresponding parameters. It is used in online() to create the basis matrices for basis smoothing.

Usage

make_basis_mats(
  x,
  n = length(x),
  mu = 0.5,
  sigma = 1,
  nonc = 0,
  tailw = 1,
  deg = 1,
  periodic = FALSE,
  idx = NULL,
  params = NULL
)

Arguments

x: The predictor variable
n: Number of knots
mu: Beta distribution location parameter
sigma: Beta distribution scale parameter
nonc: Beta distribution noncentrality parameter
tailw: Tailweight
deg: Degree of splines
periodic: Create periodic basis
idx: make_basis_mats() will create a grid containing all combinations of the parameters. If idx is set, this grid will be subsetted to the rows specified by idx.
params: Instead of the arguments above, a grid (data.frame or named matrix) of parameters can be passed directly.
