pexp_cov {smile}R Documentation

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 \sigma^2 parameter from the Exponential covariance function.

phi

the \phi parameter from the Exponential covariance function, controls the range of the spatial dependence.

nu

the \nu \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.
