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

Matern covariance function (scalar - generic)

Description

Computing the Matern covariance function for a single distance measure, adapted from geoR.

Usage

single_matern(d, sigsq, phi, nu)

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 \nu parameter from the Matern covariance function, controls the differentiability of the process.

Value

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