RMeaxxa {RandomFields}R Documentation

Special models for rotation like fields

Description

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.

Usage

RMeaxxa(E, A) 
RMetaxxa(E, A, alpha)

Arguments

E

m-variate vector of positive values

A

m\times k matrix

alpha

angle for the rotation matrix R

Details

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.

Value

RMeaxxa and RMetaxxa return an object of class RMmodel.
