\usage{
loo_linpred(object, ...)
loo_predict(object, ...)
loo_predictive_interval(object, ...)
loo_pit(object, ...)
\method{loo_pit}{default}(object, y, lw, ...)
}
\arguments{
\item{object}{The object to use.}
\item{...}{Arguments passed to methods. See the methods in the \pkg{rstanarm}
package for examples.}
\item{y}{For the default method of \code{loo_pit}, a vector of \eqn{y} values
the same length as the number of columns in the matrix used as
\code{object}.}
\item{lw}{For the default method of \code{loo_pit}, a matrix of log-weights
of the same length as the number of columns in the matrix used as
\code{object}.}
}
\value{
\code{loo_predict}, \code{loo_linpred}, and \code{loo_pit}
(probability integral transform) methods should return a vector with length
equal to the number of observations in the data.
\code{loo_predictive_interval} methods should return a two-column matrix
formatted in the same way as for \code{\link{predictive_interval}}.
