practicalRange: Pratical range for correlation functions

Description Usage Arguments Value See Also Examples

Description

Computes practical ranges for the correlation functions implemented in the geoR package

Usage

1
practicalRange(cov.model, phi, kappa = 0.5, correlation = 0.05, ...)

Arguments

cov.model

correlation model as documented in cov.spatial.

phi

correlation parameter as documented in cov.spatial.

kappa

additional correlation parameter as documented in cov.spatial.

correlation

correlation threshold for asymptotic models. Defaults to 0.05.

...

arguments to be passed to optimise.

Value

A scalar with the value of the practical range.
