\description{
  Another Glog function
}
\usage{
jglog(y, lambda)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{y}{ A matrix data }
  \item{lambda}{ Parameter that should be determined }
}
\details{
  Usually, matrix \code{y} is a modified matrix from an original matrix, after deducting parameter alpha.
  Lambda is one of the parameters that should be determined when using the glog function,
  and these parameters are decided by using the function \code{\link{tranest}}
}
\value{
  \item{yl }{ A matrix containing a transformmed values by glog}
}
