| RMiaco {RandomFields} | R Documentation |
The space-time covariance function is
C(r,t) = (1.0 + r^ν + t^λ)^δ
RMiaco(nu, lambda, delta, var, scale, Aniso, proj)
nu,lambda |
number in (0,2] |
delta |
positive number |
var,scale,Aniso,proj |
optional arguments; same meaning for any
|
RMiaco returns an object of class RMmodel.
