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

Matern (tappered) covariance function (scalar - generic)

Description

Computing the Matern covariance function for a single distance measure, addapted from geoR using Wendland-1 as a tapper.

Usage

single_tapmat(d, sigsq, phi, nu, theta)

Arguments

d	a scalar representing the distance on which it is desired to evaluate the covariance function.
sigsq	the σ^2 parameter from the Matern covariance function.
phi	the φ parameter from the Matern covariance function, controls the range of the spatial dependence.
nu	the smoothness parameter ν from the Matern covariance function, controls the differentiability of the process.
theta	the θ tapper range.

Value

a scalar representing the (tappered matern) covariance between two observations d apart of each other.
