\title{Transform between Aster Model Parameterizations}
\usage{
astertransform(arg, obj, from = c("unconditional", "conditional"),
to.cond = c("unconditional", "conditional"),
to.mean = c("mean.value", "canonical"))
}
\description{
Transform between different parameterizations of the aster model.
In effect, this function is called inside \code{\link{predict.aster}}.
Users generally do not need to call it directly.
}
\arguments{
\item{arg}{canonical parameter vector of length \code{nrow(obj$data)},
either unconditional (\eqn{\varphi}{phi})
or conditional (\eqn{\theta}{theta}) depending on the value of
argument \code{from}.}
\item{obj}{aster model object, the result of a call to \code{\link{aster}}.}
\item{from}{the type of canonical parameter which argument \code{arg} is.}
\item{to.cond}{the type of parameter we want.}
\item{to.mean}{the type of parameter we want.}
}
\value{
a vector of the same length as \code{arg}, the transformed parameter vector.
