comp_gw_covR Documentation

Generalized Wendland covariance function for a polygons.

Description

Computing the Matern covariance function between polygons.

Usage

comp_gw_cov(cross_dists, n, n2, sigsq, phi, kappa, mu)

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 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

Value

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