\title{PSIS-LOO across the ladder, as directional corroboration}
\usage{
loo_ladder(ladder, draws = 100, R = 64)
}
\arguments{
\item{ladder}{A \code{bayesqm_ladder}.}

\item{draws, R}{As in \code{\link[=loglik_person]{loglik_person()}}.}
}
\value{
A data frame: \code{K}, \code{elpd_loo}, \code{se}, \code{max_pareto_k}.
}
\description{
Person-level GHK log-likelihoods per rung, fed to PSIS-LOO. Reported as
directional corroboration only: with typical Q panels (N well below
100), differences in expected log predictive density between adjacent K
have unreliable standard errors. The GHK seeds are common across rungs,
so comparisons are common-random-number paired.
