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

Matern covariance function for a given distance matrix.

Description

Computing the Matern covariance function for a matrix of distances.

Usage

mat_cov(dists, sigsq, phi, nu)

Arguments

dists	a numeric matrix representing the distance between spatial entities.
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

The matern covariance function (for a stationary and isotropic process) associated with the provided distances (dists) and the given set of parameters.
