\tabular{ll}{
 \command{\link{RMnonstwm}} \tab one of Stein's non-stationary
 Whittle-Matern models

 \code{scale}, cf. \command{\link{RMS}}, can be any non-negative
 function for any scale mixture model, such as
 the \link{whittle-matern}-classes,
 the \link{powered exponential} family, and the
 \command{\link{RMgencauchy}} model.
