\title{Compare real and random VSS solutions}
\description{Another useful test for the number of factors is when the eigen values of a random matrix are greater than the eigen values of a a real matrix. Here we show VSS solutions to random data. A better test is probably \code{\link{fa.parallel}}.
}
\usage{
VSS.parallel(ncases, nvariables,scree=FALSE,rotate="none")
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{ncases}{Number of simulated cases }
  \item{nvariables}{ number of simulated variables }
  \item{scree}{Show a scree plot for random data -- see  \code{\link{omega}}}
  \item{rotate}{rotate="none" or rotate="varimax"}
}

\value{VSS like output to be plotted by VSS.plot
