\description{
The space-time covariance function is
\deqn{
C(r,t) = (1.0 + r^\nu + t^\lambda)^\delta
}
}
\usage{
RMiaco(nu, lambda, delta, var, scale, Aniso, proj)
}
\arguments{
\item{nu,lambda}{number in \eqn{(0,2]}}
\item{delta}{positive number}
\item{var,scale,Aniso,proj}{optional arguments; same meaning for any
\command{\link{RMmodel}}. If not passed, the above
covariance function remains unmodified.}
}
\value{
\command{\link{RMiaco}} returns an object of class \code{\link[=RMmodel-class]{RMmodel}}.
