Sets a Matern spatial correlation matrix in Gaussian copula marginal regression models.
matern.cormat(D, alpha = 0.5)
matrix with values of the distances between pairs of data locations.
value of the shape parameter of the Matern correlation class. The default alpha = 0.5 corresponds to an exponential correlation model.
An object of class cormat.gcmr
representing a Matern correlation matrix.
The Mat\'ern correlation function is inherited from the geoR
package (Diggle and Ribeiro, 2007).
