Description

Sets a Matern spatial correlation matrix in Gaussian copula marginal regression models.

Usage

matern.cormat(D, alpha = 0.5)

Arguments

D

matrix with values of the distances between pairs of data locations.

alpha

value of the shape parameter of the Matern correlation class. The default alpha = 0.5 corresponds to an exponential correlation model.

Value

An object of class cormat.gcmr representing a Matern correlation matrix.

Details

The Mat\'ern correlation function is inherited from the geoR package (Diggle and Ribeiro, 2007).
