A list containing X, a 50 x 3 design matrix, y, a vector of length 50 of observed responses, V, a 50 x 50 covariance matrix for the observed data, Xp, a 121 x 3 design matrix for the predicted responses, Vp, the 121 x 121 covariance matrix of the predicted responses, Vop, the 50 x 121 covariance matrix between the observed responses and the predicted responses, coords, a 50 x 2 matrix containing the sites of the 50 observed responses, and pcoords, a 121 x 2 matrix containing the 121 sites for the predicted responses (a 11 x 11 regular grid over the domain [0, 1]x[0, 1]).
