In smile: Spatial Misalignment: Interpolation, Linkage, and Estimation

Mean of a Generalized Wendland covariance function (Internal use)

Description

This is an auxilliary function for internal use. It helps to numerically integrate a covariance function evaluated at a grid of points within a polyigon and speed-up the computations.

Usage

aux_gw(dist, sigsq, phi, kappa, mu)

Arguments

sigsq	the σ^2 variance of the covariance function function.
phi	the φ is the range parameter of the covariance function.
kappa	κ \in \{0, …, 3 \}.
mu	μ controls the smoothness of the covariance function
dists	a numeric matrix representing the distance between spatial entities.

Value

The mean of mat_cov(dist, sigsq, phi, kappa).
