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

Powered Exponential covariance function for a given distance matrix.

Description

Computing the Matern covariance function for a matrix of distances.

Usage

pexp_cov(dists, sigsq, phi, nu)

Arguments

dists	a numeric matrix representing the distance between spatial entities.
sigsq	the σ^2 parameter from the Exponential covariance function.
phi	the φ parameter from the Exponential covariance function, controls the range of the spatial dependence.
nu	the ν \in (0, 2] parameter representing the "power"

Value

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