single_exp {smile}R Documentation

Exponential covariance function (scalar)

Description

Computing the Exponential covariance function for a single distance measure.

Usage

single_exp(d, sigsq, phi)

Arguments

d

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

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.

Value

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