aux_tapmat {smile}R Documentation

Mean of a (Matern - Wendland-1 tapper) covariance function (Internal use)

Description

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

Usage

aux_tapmat(dist, sigsq, phi, nu, theta)

Arguments

dist

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,

nu

smoothness parameter

theta

the \theta tapper range.

Value

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