single_tapmat3 {smile}R Documentation

Tapered Matern covariance function (scalar - nu = 3/2)

Description

Computing the Matern covariance function for a single distance measure, with \nu = 3/2.

Usage

single_tapmat3(d, sigsq, phi, theta)

Arguments

d

a scalar representing the distance on which it is desired to evaluate the covariance function.

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.

theta

\theta taper range.

Value

a scalar representing the (tapered matern) covariance between two observations d apart of each other.
