Mean of a (Powered Exponential) covariance function (Internal use)

Description

This is an auxilliary function for internal use. It helps to numerically integrate a covariance function evaluated at a grid of points within a polyigon and speed-up the computations.

Usage

aux_pexp(dist, sigsq, phi, nu)

Arguments

sigsq	the σ^2 parameter from the Powered Exponential covariance function.
phi	the φ parameter from the Powered Exponential covariance function, controls the range of the spatial dependence.
nu	the ν parameter from the Powered Exponential covariance function, controls the differentiability of the process.
dists	a numeric matrix representing the distance between spatial entities.

Value

The mean of pexp_cov(dist, sigsq, phi, nu).
