comp_tapmat_cov: Wendland-1 covariance function for a polygons.

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

Wendland-1 covariance function for a polygons.

Description

Computing the Matern covariance function between polygons.

Usage

comp_tapmat_cov(cross_dists, n, n2, sigsq, phi, nu, theta)

Arguments

cross_dists	a list such that each position contains the cross distances between points within different polygons.
n	an ingeger representing number of polygons (note that, this is different than the size of the list cross_dists
n2	usually, equal to n, except when the function is being used to calculate the "cross" covariance between two different partitions of the same space.
sigsq	the σ^2 parameter from the Matern covariance function.
phi	the φ parameter from the Matern covariance function
nu	the smoothness parameter ν parameter from the Matern covariance function
theta	the taper distance.

Value

The wendland-1 covariance matrix associated with a set of polygons.
