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

Matern (tapered) covariance function (scalar - generic)

Description

Computing the Matern covariance function for a single distance measure, adapted 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 \sigma^2 parameter from the Matern covariance function.
phi	the \phi parameter from the Matern covariance function, controls the range of the spatial dependence.
nu	the smoothness parameter \nu from the Matern covariance function, controls the differentiability of the process.
theta	the \theta tapper range.

Value

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