matern.cormat | R Documentation |
Sets a Matern spatial correlation matrix in Gaussian copula marginal regression models.
matern.cormat(D, alpha = 0.5)
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. |
The Mat\'ern correlation function is inherited from the geoR
package (Diggle and Ribeiro, 2007).
An object of class cormat.gcmr
