kMatern | R Documentation |
Matérn kernels, obtained by plugging the Euclidian norm into a 1-dimensional Matérn function.
kMatern(d, nu = "5/2")
d |
Dimension. |
nu |
Character corresponding to the smoothness parameter |
An object of class "covMan"
with default parameters: 1 for
ranges and variance values.
Notice that these kernels are NOT obtained by tensor product.
