initialize_basisfun_inducingpt: Initialize parameters for inducing-point basis functions

In SLGP: Spatial Logistic Gaussian Process for Field Density Estimation

Initialize parameters for inducing-point basis functions

Description

Computes kernel matrix and its decompositions for use in inducing-point basis functions.

Usage

initialize_basisfun_inducingpt(
  dimension,
  kernel = "Mat52",
  lengthscale,
  pointscoord = NULL,
  numberPoints = NULL
)

Arguments

dimension	Integer. Input ([\mathbf{x},\,t]) dimension.
kernel	Character. Kernel type ("Exp", "Mat32", "Mat52", "Gaussian").
lengthscale	Numeric vector. Lengthscales used for scaling the input space.
pointscoord	Optional matrix of inducing point coordinates. If none is provided, we sample them uniformly in the unit hypercube.
numberPoints	Integer. Number of inducing points (used if pointscoord is NULL).

Value

List with kernel square root and inverse root matrices, and scaled coordinates.
