| RMeaxxa {RandomFields} | R Documentation |
RMeaxxa and RMetaxxa define the auxiliary functions
f(h) = h^\top A A^\top h + diag(E)
and
f(h) = h^\top A R R A^\top h + diag(E)
respectively.
RMeaxxa(E, A)
RMetaxxa(E, A, alpha)
E |
m-variate vector of positive values |
A |
|
alpha |
angle for the rotation matrix |
RMeaxxa is defined in space and returns an m-variate model.
RMetaxxa is a space-time model with two spatial dimensions.
The matrix R is a rotation matrix with angle \beta t where
t is the time component.
RMeaxxa and RMetaxxa return an
object of class RMmodel.
